Protista By: Dhyana Chudasama and Nimi Vasipalli Movement Euglenas- Whips its flagellum around like a helicopter propeller. Paramecium- moves with the help of cilia. Algae- The movements of the algae’s flagella are synchronised by mechanical forces. Its swimming strokes accelerate or slow down depending on how the cell rocks while swimming. Amoebas- To moved, amoebas form temporary cytoplasmic extensions called pseudopodia, or false feet. Algae Functions Algae - Produce oxygen and is the base of the marine food chain. Euglena - photosynthesize: taking in carbon dioxide and releasing oxygen into the atmosphere so that other organisms can survive. Paramecia - Help control algae, bacteria, and other protists that can be found in water. Amoeba - food vacuole - within the amoeba where food is digested nucleus -it controls reproduction - contains the chromosomes and eating and growth amoeba Number of Cells Protists are unicellular and multicellular Example: Algae - multicellular Euglena - Unicellular Algae Cell Walls Protists’ cells walls are composed of cellulose as opposed to peptidoglycan like the other kingdom’s cells are composed of
