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? a the euglena will move toward the sunlight in order to produce glucose. b the euglena will have no response to the sunlight since the are consumers. c the euglena will move away from the sunlight in order to prevent drying out. d the euglena will move toward darkened areas in the water in order to find food.
Answer
Brief Explanations:
Euglena has chlorophyll and an eye - spot to detect light. Since it can perform photosynthesis (using light to produce glucose), when exposed to sunlight, it will move toward the sunlight to get the energy source for photosynthesis. Option B is wrong as euglena can photosynthesize (not just consumers). Option C is wrong as moving away from sunlight would not help in photosynthesis. Option D is wrong as moving to darkened areas is not for food in this context (it can make food via photosynthesis with light). So the correct option is A.
Answer:
A. The euglena will move toward the sunlight in order to produce glucose.
