Q
  1. What are the various nutritional modes of Protists?
A
  1. Photoautotrophs
  2. Heterotrophs
  3. Mixotrophs
17
Q
  1. What are Photoautotrophs?
A
  • these are protists that contain chloroplasts
  • they perform photosynthesis

EXAMPLE:
- Algaes

18
Q
  1. What are Heterotrophs?
A
  • these are protists that absorb organic molecules
  • or they ingest larger food particles
  • through the process of Phagocytosis

EXAMPLE:
- Amoeba

19
Q
  1. What are Mixotrophs?
A
  • these are protists that combine photosynthesis
    and heterotrophic nutrition
20
