Q

Golgi Apparatus (G.A.)

A

S =folded membranes within the cytoplasm F = proteins move to the GA where they are bound into vesicles. These are stored until needed.

Q

Lysosomes

A

S = membrane-bound cell organelle F= They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
