Which controls the movement of waste out of the cell?

Answer
A
mitochondrion
B
cell membrane
C
ribosome
D
chloroplast

Explanation

The cell membrane surrounds the cell and regulates which substances enter and leave it, including waste products. Mitochondria release energy, ribosomes make proteins, and chloroplasts carry out photosynthesis, so the cell membrane is the structure that controls waste movement.
