Q.
Chlorophyll in chloroplast is located in
AIPMTAIPMT 2005Cell : The Unit of Life
Solution:
A chloroplast is a vesicle bounded by an envelope of two unit membranes and filled with a fluid ; matrix called stroma. The lamellae, after separation from the inner membrane, usually take the form of closed, flattened, ovoid sacs, the thylakoids, which lie closely packed in piles, the grana. The thylakoid membrane contains photosynthetic pigments namely, chlorophyll a, chlorophyll b, carotenoids (carotene, xanthophylls) and plastoquinone. The thylakoid membranes also contain : coupling factors that bring about ATP synthesis.
