14)
Euglena is a one-celled protist that has traits of both plant and animal cells. It contains chlorophyll and has an
eye spot to detect light. Yet, it has a flagella for movement through its aquatic environment and can ingest food
through its gullet.
A colony of euglena are exposed to sunlight. Based on the traits of this organisms, what would you expect to
happen?
The euglena will
move away from
A) The euglena will move toward the sunlight in order to produce glucose.
C) the sunlight in
order to prevent
drying out.
The euglena will
move toward
B) The euglena will have no response to the sunlight since the are consumers.
D) darkened areas in
the water in order
to find food.

A) vacuole.
C) cytoplasm.
B) cell wall.
D) cell membrane.
