Document Summary

Tree of life: protists: structure: most are unicellular (and microscopic) Unicellular protists may group together and work together in a colony, but can branch off and be on their own any time. Contractile vacuole: pumps water to prevent lysis (disintegration of cells) in freshwater. Pellicle: layer of supportive protein fibers under plasma membrane. Important for protists that have a defined structure and need to move from making a way through a material, or in between cells. Both flexible and has a structural integrity (can maintain its shape) Pseudopodia: lobes of cytoplasm allow amoeboid (amoeba-like) movement. How amoeboid protists move, flow forward to allow amoeboid movement. Have a plasma membrane that can change its shape https://onedrive. live. com/edit. aspx/documents/biology?cid=4612573e81e7633b&id=documents&wd=target%28september. one%7caa4f95b0-28e4 1/11. Bc they have a cell membrane, things can move thru the cell membrane and into the cell, diffusion. Protist diversity (cont"d: locomotion: motile (most, at least 1 life history stage) Swimming via flagella or cilia, anchored to the pellicle.
