The photosynthetic pigments were removed from their “natural” spot in cells during extraction – where?
1. mitochondrial matrix
2. chloroplast stroma
3. mitochondrial inner membrane
4. chloroplast thylakoid membrane
Chlorophyll is the only pigment in plant leaves.

Verified answer
1 - 4
2- False there are other pigments like carotene, Xanthophylls, Phaeophytins
3 - this depends on the polarity of the mobile phase. chemically carotinoids are more polar than chlorophylls. Actually chlorophyll b is the least polar and carotene is the highest polar. Chlorophyll a comes as the 2nd least polar and xanthophyll should come between chlorophyll b and carotene. But if you use only ether as mobile phase for example carotene will have the highest attraction for paper. So this solely depends on the polarity of the mobile phase.
i imagine of you're over-wondering this. the shape interior the plant cellular that absorbs gentle is the chloroplast. it is the organelle which consists of chlorophyll and different molecules that react with the gentle and start up the electron delivery chain interior the technique of photosynthesis, and that is what i imagine of the question grew to develop into into going for. If it were my class, though, i'd furnish you a minimum of partial credit for information what thylakoids are, so possibly your instructor will do an similar.
