What is the difference between autotrophic and heterotrophic organisms?

Back

Autotrophic organisms produce their own food (e.g., through photosynthesis), while heterotrophic organisms obtain food by consuming other organisms.

What is an Amoeba?

Back

Amoeba is a type of single-celled organism that moves and feeds using pseudopods, which are temporary projections of the cell.

What is the role of flagella in protists?

Back

Flagella are long, whip-like structures that help some protists move through their environment.
