Question

Identify the functions of the labeled structures.

Nucleus

controls what enters and leaves the cell

directs cell activity

breaks down waste material and debris
An animal cell is labeled with the nucleus and ribosomes.

Answer 1

Here are the matches and brief functions:

- Nucleus — directs cell activity (stores the cell’s DNA and controls growth, metabolism and reproduction).
- Controls what enters and leaves the cell — plasma membrane (cell membrane).
- Breaks down waste material and debris — lysosome (contains digestive enzymes).
- Ribosomes (also labeled in the cell) — synthesize proteins (site of protein production, free in cytoplasm or on rough ER).
