Biology presentations presentation for a biology lesson (grade 7) on the topic. Amphibians and reptiles

SYSTEMATICS - biological science about diversity, classification of organisms and the relationship between them.

Systematics scientists describe all existing and extinct species and combine them into groups (classify).

View - a unit of biological classification. Closely related species, which have many common features, are combined into genera, childbirth - in families, families - in detachments or orders etc.

The largest systematic group is kingdom.

The very first scientist who tried to systematize information about plants and animals was Aristotle b. Animals were classified by him according to their habitat: aquatic, land and airborne.

Disciple of Aristotle Theophrastus he devoted his whole life to the study of plants and described many of their species. For centuries, his works have served to identify plants.

The entire history of mankind is associated with the accumulation of knowledge about plants, animals and mushrooms. However, for a long time there was no unified approach to the names of species of living organisms. This made it difficult to study and describe them.

The Swedish scientist managed to solve the problem Karl Linnaeus .

He proposed to assign to all types of organisms double Latin names . The first word - noun - shows family affiliation . Second word - adjective - actually species name to distinguish a given species from other species of the same genus. The introduction of double Latin names allowed scientists all over the world to understand each other, contributed to the development of biological science.

Homework: §8, answer to?

The group of amphibians belongs to the most primitive terrestrial vertebrates, occupying an intermediate position between terrestrial and aquatic vertebrates: reproduction and development in most species occurs in the aquatic environment, and adults live on land.

Most live in humid places, alternating between being on land and in water, but there are some purely aquatic species, as well as species that live exclusively in trees. Insufficient adaptability of amphibians to living in a terrestrial environment leads to sharp changes in their lifestyle due to seasonal changes in living conditions. Amphibians are capable of hibernating for a long time under unfavorable conditions (cold, drought, etc.). In some species, activity can change from night to day when temperatures drop at night. Amphibians are active only in warm conditions. At a temperature of ° C, most species fall into a daze, and at 1 ° C they die. But some amphibians are able to withstand prolonged freezing, drying out, and also regenerate significant lost body parts.

Some amphibians, such as the sea toad Bufo marinus, can live in salt water. However, most amphibians are found only in fresh water. Therefore, they are absent on most oceanic islands, where conditions are in principle favorable for them, but which they cannot reach on their own.

All modern amphibians are predators in the adult stage, feed on small animals (mainly insects and invertebrates), and are prone to cannibalism. There are no herbivorous animals among amphibians due to extremely sluggish metabolism. The diet of aquatic species may include juvenile fish, and the largest ones can hunt chicks of waterfowl and small rodents that have fallen into the water.

A common breeding feature of almost all amphibians is their attachment during this period to water, where they lay their eggs and where the larvae develop. Amphibians breed in small, well-warmed areas of water bodies. On warm spring evenings, in late April and May, loud croaking sounds are heard from the ponds. These "concerts" are organized by male frogs to attract females. The reproductive organs in males are testes, in females there are ovaries. Fertilization is external. Caviar sticks to aquatic plants or rocks.

The most poisonous vertebrates on Earth belong to the order of amphibians - the dart frogs. The venom secreted by the skin glands of amphibians contains substances that kill bacteria (bactericides). In the majority of amphibians in Russia, the poison is completely harmless to humans. However, many tropical frogs are not as safe.

The absolute "champion" of poisonousness among all vertebrates, including snakes, should be recognized as an inhabitant of the rainforests of Colombia, a tiny, only 23 cm in size, terrible leaf climber (locals call him "cocoi" Her skin mucus contains batrachotoxin. Indians prepare poison from the skin of "cocoi" for arrows. One frog is enough to poison 50 arrows. 2 mg of purified poison is enough to kill a person. However, this frog has a natural enemy the small snake Leimadophis epinephelus, which feeds on young leaf crawlers.

All amphibians, to one degree or another, are useful for humans, primarily because they eat many harmful invertebrates that damage agricultural and forest crops or carry diseases of humans and domestic animals. In terrestrial species, food items are usually more diverse than in species with an aquatic lifestyle. The common frog eats 6 harmful invertebrates on average per day. With a population of 100 frogs per hectare, they will destroy more than 100 thousand pests during the period of summer activity.

In a number of countries, large salamanders and frogs are used for food by people (France, Southeast Asia, America, etc.). There are farms in the USA that breed bullfrog; the hind legs (pair weighing g) go on sale, and the rest of the carcasses are processed for livestock feed.

Amphibians are very important as laboratory animals used in a wide variety of biological and medical research. In several countries Western Europe the number of many amphibians has dropped sharply. The reasons for this are various: changes in habitats as a result of land reclamation and economic development of territories, water pollution in spawning reservoirs, persecution by humans, etc. Therefore, in some countries, special laws have now been adopted to protect amphibians and prohibit their extraction. For laboratory purposes, axolotls are bred, attempts are being made to artificially breed other species.

Enrichment of blood with oxygen occurs in the lungs, and saturation with nutrients - in the digestive organs. In the liver and kidneys, there is a neutralization and removal of metabolic products. Blood circulation is regulated by hormones and the nervous system. Blood circulation is an important factor in the life of the human body and a number of animals. The large vessels that carry blood to organs and tissues are called arteries. Arteries branch out into smaller arteries, arterioles, and finally capillaries. -

History of the discovery of sponges

Zoologists still do not know exactly where, in what place of the animal kingdom to place the sponges. Sponges received the status of animal organisms only in 1825 ., and before that, together with some other sedentary animals, they were classified as zoophytes - semi-animals, semi-plants.

• Single or colonial, having a calcareous (Lime) or silicon skeleton (Glass and Ordinary), sizes from 1mm (Glass) to 1m (Ordinary);
• Predators and filter feeders;
• Well developed passive protection in the form of needles, release of a repelling odor, poisonous substances to protect against enemies and immobilize animals (bacteria, protozoa)
• Lack of true tissues and germ layers

Dimensions vary widely: from a few millimeters to one meter in height or more . A sponge taken out of water resembles a piece of raw liver and smells bad

Habitat .

Sponges are extremely common animals in the aquatic world of our planet. They are found in the icy water of the Arctic and Antarctic, and in the tropics, in salt and fresh water bodies.

But the species diversity of sponges most in the salty waters of warm latitudes, tropics and subtropics.

The shape of the body can be extremely variable, often resembling a glass or a bag. The color varies from bright yellow to dark brown.

• The body of sponges consists of different types of cells.

• But they do not form tissues. Each cell functions independently.

• Outer layer the bodies of the sponges form cells that resemble those of the integumentary epithelium of other multicellular animals. Among the cells of the outer layer, there are those that have a pore. These pores begin the tubular system that penetrates the walls of the body. The openings of these tubules are surrounded by cells that can contract and close them. The tubules carry water with food particles to the inner cavity.

• This cavity is usually lined with special cells with flagella, the base of which is surrounded by a membranous collar (Fig. 58, Such cells form the inner layer .

In many sponges, they are located inside the body walls, forming flagellar chambers. The work of the flagella ensures the movement of water through the tubule system and internally

• Between the outer and inner layers of cells is intercellular substance, in which different types of cells are located. Some of them form the internal skeleton of the sponges.
• Another type of cells - amoeboid. These cells, using pseudopods, capture food particles that are digested in their

digestive vacuoles. Moving along the body of the sponge, amoeboid cells distribute nutrients.

The main types of structure of the aquifer system of sponges

leacon

ascon

sicon

Ascon

In a number of Calcareous sponges, an increase in the size of the flagellar chambers and a reduction in the system of inlet and outlet channels occurred. Such sponges consist of a tube or branched tube system lined with choanocytes from the inside; the pores (ostia) open directly into the flagellar chambers. The aquifer is characteristic of only two genera - Leucosolenia and Clathrina .

Sicon

The formation of the sicon is caused by the proliferation of the mesochila and the invagination into it of the sections of the paragastric cavity that form the radial tubes. Choanocytes line only the flagellar tubes and disappear from other parts of the atrial cavity. The walls of the body of the sponge thicken, and the leading channels are formed between the surface of the body and the flagellar tubes. The structure of the siconal type is characteristic of only a few species (for example, for Scypha and Grantia).

Leikon

The most complex type of structure. These are colonial sponges with numerous osculums. There are many skeletal elements in the thick layer of mesoglea. The body wall is penetrated by a network of channels connecting numerous flagellar chambers

CONCLUSIONS

The sponge feeds on those food particles that water brings. This is the simplest type of sponge structure - ascon ... But in most sponges, a thickening of the mesoglea occurs and flagellate cells line the invaginations, cavities. This type of structure is called sicon , and when these cavities completely go inside the mesoglea and are connected by channels with the paragastric cavity - leacon .

Sponges, moreover, usually form colonies with many openings on the surface: in the form of crusts, lumps of lumps, bushes.

Fig 3.3. Development of limestone sponge

(according to Schulze):

1 - the embryo in the body of the maternal individual, large cells stuck inside the blastocoel cavity; 2 - free-swimming larva, large cells protruded again; 3 - invagination of small cells carrying flagella (gastrulation); 4 - attachment and beginning of larval metamorphosis.

In addition to asexual reproduction - budding, sponges also reproduce sexually. The way the larva develops is remarkable. From the ovum, a blastula develops, consisting of one layer of cells, and at one pole the cells are small and with flagella, at the other - large ones without flagella. First, large cells invade inward (1), then protrude and the larva floats freely (2), then flagellate cells invaginate again, which become the inner layer (3).

The larva settles and turns into a young sponge (4).

The peculiarities of the embryonic development of sponges give reason to scientists to believe that in them the primary ectoderm (small flagellate cells) replaces the endoderm. There is a perversion of the embryonic layers. On this basis, zoologists give the name to the sponges - animals turned inside out (Enantiozoa). Interestingly, the larva of most sponges is a parenchymula, in structure almost completely corresponding to the hypothetical phagocytella of II Mechnikov. It has a surface layer of flagellate cells, under which the cells of the inner loose layer are located. It can be assumed that the phagocytella switched to a sedentary lifestyle and in this way gave rise to the Sponge type. Another feature is the amazing ability of the sponges to regenerate. Even when rubbed through a sieve and turned into a slurry consisting of cells or groups of cells, they are capable of restoring the body. If you rub two sponges through a sieve and mix these masses, then the cells of different animals will gather in two different sponges.

In nature, sponges are essential as biofilters. Settling in reservoirs with significant organic pollution, they participate in their biological treatment. The practical value of sponges is not great. In some southern countries, the fishery of toilet sponges with a horny skeleton is developed; a freshwater sponge is used in folk medicine. The sponges have practically no enemies, except for some sea stars. Others are frightened off not only by the spiky skeleton, but also by the sharp, specific smell of the substances they release. These substances are toxic to many animals. But on the other hand, the sponges in the cavities and voids have many tenants and parasites - small crustaceans, worms, mollusks living under their protection.

REPRODUCTION OF SPONGES

Most sponges hermaphrodites ... Reproduction sexual and asexual. The kidneys that form on the body, as a rule, do not separate from the mother's body, which leads to the appearance of colonies of the most bizarre shape. In the sexual process, the sperm fertilizes the egg; a larva emerges from the egg, swimming for a while in the water, and then attaching itself to the bottom. Most sponges live from a few weeks to two years; horse sponge can live up to 50 years or more.

Reproduction of sponges

Larva

The sperm are released into the water and enter the body

other sponges where eggs are fertilized . .

Asexual reproduction by external budding

Reproduction of sponges

A different way of internal budding exists in the freshwater sponge badyagi. In the summer, badyaga reproduces by ordinary budding and sexually. But by autumn, in the mesoglea of \u200b\u200bbadyagi, the formation of special globular clusters - gemmules - by amoeboid cells is observed. Gemmula is a multicellular mass surrounded by a membrane of two stratum corneum, between which there is an air layer with small silica needles, placed perpendicular to the surface of the gemmule. In winter, the body of the badyagi dies and disintegrates, and the gemmules fall to the bottom and, protected by their shell, remain until the next spring. Then the cell mass contained inside the gemmule crawls out, attaches to the bottom and develops into a new sponge

Regeneration of sponges

Sponges have a very well-developed ability to tissue regeneration : even if the sponge is cut into pieces, a new sponge will grow out of each piece after a while.

Survival sponges

The ability of freshwater sponges to endure unfavorable living conditions is remarkable. Their gemmules are very well preserved even for several years. When a reservoir dries up completely, for example, they can be carried to other places in a variety of ways, including with the help of the wind or by attaching to the legs of birds. And if such gemmules get into the water, they give rise to a new settlement of sponges.
