A. Helps cell maintain
cell shape.
Spherical shaped. Sacs.
Use oxygen to break
down fats.
Pair structure. Small set
of microtubules.
Help cell divide.
Like many little hairs.
Example: Lining of
windpipe.
1. Movement in
unicellular organisms.
2. Use cilia to move
fluid over the surface.
Generally longer than
cilia and limited to one
or a few per cell.
