Compare the similarities and differences in the morphological structure of Euglena, paramecium, and

Eukaryotic substances: paramecium, yeast, chlamydomonas, amoeba, sunworm, trumpet worm, malaria parasite and other unicellular eukaryotic algae: chlamydomonas, coccus, algae, sluice algae and other substances are not prokaryotic unicellular substances.

One is a single-celled eukaryotic organism that is somewhere between animals and plants.

One is protozoa. Single-celled eukaryotes are small in size and can independently complete all the physiological functions of life activities. Protozoa: Any tiny, single-celled protist that can often only be observed under a microscope. The two are different.

It is a general term for Euglena organisms, called euglena in botany, and is a class of single-celled eukaryotes between animals and plants that live in ditches, ponds or slow streams rich in organic matter. However, it is also found in river banks, bay wetlands or saline marshes, as well as on other algal bodies, plant fragments, and small crustacean bodies.

Paramecium has a relatively complex structure, which is the ontological structure and basic structure of the cell.

Additional information: Paramecium is a small, cylindrical protozoa. It is made up of only one cell and is a single-celled protozoan, hermaphroditic.

The most common is Cercocerium paramecium. The body length is only 180 to 280 microns. It and amoeba have the shortest lifespan, measured in hours, and the lifespan is about a day and night.

Paramecium can live up to more than five days and nights. It is called paramecium because its body shape looks like an upside-down straw sole from a flat perspective.

Paramecium is responsible for the swing of cilia by using a special arrangement of vascular tubes on the body, which is the fastest type of protozoa, when paramecium swims, the cilia swing will be like a boat oar, retracting and releasing to propel the body forward. If an obstacle is encountered at the same time as the advance, the cilia will move in the opposite direction, retreat and then change direction to move forward and change the mountain later.

Paramecium mainly feeds on aquatic bacteria and other aquatic organic matter, and is selective for different bacteria. The ciliary oscillation of paramecium not only helps them move their bodies, but also allows them to move food into the gutter with the flow of water, forming food vacuoles, which are then gradually digested in the vesicles with the flow of cytoplasm, and the indigestible residues are discharged from the body through the anal orifice of the cells on the epigraphic.

There are many varieties with different living habits, and they are characterized by having a hard shell.
