Is paramecium prokaryotes?
Paramecium is a very small, cylindrical single-celled organism, androgynous, with a body length of only 180 μ m and a life span of about one day and night. living in fresh water, it can be collected in ponds and streams, generally in the shape of a long cylinder, blunt front end, wide and slightly pointed rear end, and straw sandals shaped like inverted sandals. Let's take a look at whether paramecium is prokaryote.
Is paramecium prokaryotes?
Paramecium is eukaryote. Paramecium is not only the representative species of ciliates, but also the representative species of protozoa. It is a single-celled organism of protozoa, ciliata, hymenostoma, paramecium and paramecium. It lives in ponds, slow-flowing ditches, rivers and ditches near residential areas. Paramecium is a larger species of protozoa, with the naked eye to observe the liquid containing a large number of paramecium, you can see a lot of needle-like bright white dots floating, these white spots are paramecium.
What kind of food does paramecium eat?
The paramecium's body is full of cytoplasm, constantly swinging the cilia in the mouth groove, bulging the water vortex, ingesting bacteria, small organisms and decaying organic matter in the water. Although most paramecium are fully nutritious, the exception is Paramecium, which contains symbiotic green algae, which can use nitrogenous waste excreted by animals as a source of inorganic salts to produce organic matter through plant photosynthesis.
How does paramecium digest food?
Paramecium has complex digestive organelles. There is an oral groove near the front end of the paramecium, which extends obliquely to the middle of the body. The end of the oral groove is connected with the surface membrane to form a cell mouth, which is connected with a funnel-shaped pharynx. Food enters the cell mouth by swinging cilia at the mouth groove, accumulates into inferior vesicles at the lower end of the pharynx, is wrapped by the cytoplasm, forms food bubbles, flows in a fixed path, and is digested after fusion with lysosomes. finally, the indigestible residue is excreted from the anus at the back of the body.
