What are Protists? Protists are unicellular organisms that means they are made up of only one cell. They are Eukaryotic cells. Some protists are amoeba, volvox, paramecium, and Euglena.
The Protist , Protozoa, Algae and Fungus-like protists
The amoeba is a unicellular organism which means it is made of one cell. They're to small to see without a microscope and are often found within a ponds or lakes. They eat algae, bacteria, plant cells, and other unicellular organisms. They move by changing from a solid state to a liquid form this is in the cytoplasm. They reproduce by splitting into two this is called fission this type is called "A Sexual Reproduction". Some amoebas are parasites which can cause diseases it is transmitted by contaminated water.

The Euglena is a unicellular organism which is a one celled organism. The Euglena move by the flagellum which is a long whip-like structure that acts like a small motor. The Euglena makes it food with photosynthesis and absorbing nutrients. The Euglena reproduces by splitting into two the DNA of the cell is the same it is identical. This is Binary Fission which is A Sexual Reproduction. It responds to the environment it has a eyespot this tells the cell where light it where it can do photosynthesis and produce food.
Euglena - Longitudinal binary fission
The paramecium is a unicellular organism this means it is made up of only one cell. The paramecium moves by using the cilia the shape of it is hair-like size. It eats by using it's cilia to sweep food into it's oral groove. The paramecium reproduces by Binary Fission the cell splits into and conjugation. The paramecium responds to the environment by having trichocysts which protects them things that endanger them.

Volvox are unicellular are one celled organisms algae that live together in a colony. The volvox gets food from photosynthesis which is when food is produced. The volvox moves with it's two flagella they hit against each other to roll the ball through the water. The volvox reproduces by producing daughter colonies. The volvox responds to the environment by staying together in colonies.
