Question

The chloroplast is a membrane-bound organelle that is surrounded by an outer membrane. Aside from the outer membrane of the chloroplast, how many other types of membranes can be found inside the chloroplast?

A. 0
B. 1
C. 2
D. 3
E. 4

Answer 1

The chloroplast has two other types of membranes inside it besides the outer membrane: the inner membrane and the thylakoid membrane system.

Step-by-step explanation:

The chloroplast, an organelle involved in photosynthesis, has multiple types of membranes within it. Besides the outer membrane, there are two other types of membranes inside the chloroplast: the inner membrane and the thylakoid membrane system. The thylakoid system is a collection of folded membrane sacs where chlorophyll and the light reactions of photosynthesis occur. Stacks of thylakoids called grana are found within the chloroplast's inner membrane, and the fluid enclosed by the inner membrane is called the stroma.
