Question

Explanation of steps performed by holozoic nutrition

Answer 1

An example would be Amoeba:

- It uses finger like projections called “pseudopodia” which fuse around the food particle to form a food vacuole.

- Within the food vacuole, complex substances are broken into simpler substances, which diffuse into the cytoplasm.

- The undigested waste material is then taken to the edge of the cell and thrown out.
