strokes accelerate or slow down
depending on how the cell rocks

Functions
Algae - Produce oxygen and is the base of the
marine food chain.

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

Cell Walls
Protists’ cells walls are composed of
cellulose as opposed to
