Pictured is a ribosome. how are ribosomes different from most other cell organelles?
a. they are transported through the plasma membrane.
b. they are generally located outside the cell.
c. they are not enclosed by a membrane.
d. they contain dna.

C. They are not enclosed by a membrane. 

D is incorrect because Ribosomes do not contain DNA, the nucleolus does.
B is also incorrect because they aren't located outside the cell, they're in the cell, on the endoplasmic reticulum.

Hoped this helped :)
