Anatomy The protista can be broken down into four catergories on how they move. - Zooflagellates move by flagellum. - Sarcodines move by the extension of cytoplasm. - Ciliates move by cilia. - Sporozoans which don’t move. Protists are mostly unicellular organisms, but some are multicellular. All are eukaryotic. (have a true nucleus) (Phytoplankton) ↑

Physiology Most protists are translucent. Come on many different colours depending on the species. Predominantly unicellular and contains many similar organelles. These organelles include Nuclei, mitochondria and choroplasts.

Locomotion There are four different ways protists can move. - Flagellum: This is a tail like structure that allows the cell to move by swimming and by the extension of the tail. -Cytoplasm: The extension of cytoplasm. -Ciliates: hundreds of small leg like structures. Cilia in a protist. ↑

Obtaining Food Since protists are unicellular and full organism they obtain the same way any other organism would but digest it the way a cell would. Amoebas consume by surrounding the prey and consume using diffusion. Many types of protists however can get energy through photosynthesis such as noctiluca. Noctiluca ↑

Diet Depending on the phylum a protist is in, they consume different things. Algal protists and pytoplankton use photosynthesis to get their food.

Digestion Protozoans (Animal like protist) digests food through their cytostome, and uses their cytopyge to get rid of their waste. The way protists digest depends on if they are animal like, plants like or even fungi like.

Exertion Depending on the category the protist fits under (animal like, plant like or fungi like) it gets rid of their waste through their endoplasmic rectilium or cytopyge.

Respiration In general most protists require oxygen to perform respiration. Two types of protists however can do respiration without oxygen. Some parasitic protists and bottom dwelling ciliates.

Circulation Protiens and waste are circulated throughout the protist through the cytoplasm by using endocytosis. Diffusion is responsible for circulation.

Life Cycle Amoebas- an amoeba’s life cycle begins when an old existing amoeba subdivides and creates new amoeba that looks identical to the pre existing amoeba except smaller. The amoeba then subdivides and creates more amoebas.
