Species of protozoa

Foraminifera — a special group of animals living in the seas. They are characterized by the presence of shells. The magnitude of the sinks is very small, only some forms the shell is almost 6 see the composition of all marine sedimentary rocks composed of the shells of dead foraminifera. In the composition of the chalk used in schools, you can find the calcareous shells of foraminifera previously lived.

Euglena green consists of cytoplasm and nucleus. The outer layer of the cytoplasm is more dense than the internal. In the body of a euglena green chromatophores. In the light she eats, like a plant absorbs inorganic matter, creating organic. In the dark green euglena is nourished like an animal: ready absorbs organic substances.

The malaria Plasmodium — the causative agent of malaria in humans. The lifecycle of Plasmodium falciparum takes place not in one host. Asexual reproduction of Plasmodium falciparum occurs in human blood, and sexual — in the gut of Anopheles mosquito.

Human infection occurs by the bite of a mosquito. In the saliva of the mosquito is the malaria parasite — malaria parasites (sporozoite). Sporozoites penetrate the liver of the human, then the human blood cell, where they are increased asexual reproduction. The output of each generation of erythrocytes in the blood plasma is accompanied by fever, because this time the blood gets poisonous substances.

After several asexual generations appear sexual beings.

In the blood accumulate sexual beings, but do not develop. Further developmental cycle of Plasmodium falciparum continues only in the mosquito the mosquito: there is sexual reproduction and the formation of the asexual generation.

The Shoe is quite large among the simplest single-celled animal that lives in fresh water. Body shoes covered with a dense shell with cilia. Swims slipper cilia. The function of the cilia located near the mouth of the recess, connected with the supply: atrial Dignam of the cilia is called the water current. Along with bacteria and other small pond inhabitants of the slipper swallowed the water. Inside the body of the Shoe is formed the digestive vacuole.

As to digestion, vacuole makes movements. In a certain place is the ejection of undigested food residue.

Tufelka reproduces asexually and sexually. Changing these ways of multiplication occurs through several generations.
