Rough ER differs from smooth ER in that
- rough ER is found only in plants
- rough ER carries chlorophyll
- rough ER has ribosomes, smooth doesn't
- rough ER sits inside the nucleus
Show answer and solution
Correct answer: C. rough ER has ribosomes, smooth doesn't
The 'rough' look comes from ribosomes studded on the ER membrane. They make proteins.
Smooth ER has no surface ribosomes
it handles lipid synthesis and detoxification.
Both forms exist in plants and animals
ER is in the cytoplasm
chlorophyll lives in chloroplasts.
