LOCOMOTION
* the
ability of an organism to move (by itself) from place to place
* locomotion increased the probability of survival among animals and
many protists
ADVANTAGES OF LOCOMOTION
1) increased opportunities to locate food
2) increased ability to seek shelter
3) increased ability to avoid from predators
4) increased ability to move from toxic wastes5) increased opportunities to locate mates
ADAPTATIONS FOR LOCOMOTION
I. Protists
A) Protozoans
1) cilia: short hair-like projections of the cytoplasm that are common to paramecia
2) pseudopods: cytoplasmic extensions resembling "feet" which enable amebas to move
3) flagella: a long, whip-like structure found in certain algae and sometimes protozoans
II. Plants
PLANTS
DO NOT MOVE
THEY ARE CALLED SESSILE
(when have you ever seen a plant move from place to place by itself?)
