Question: why is the chloroplasts in plants green? can they not be pink, or blue, or red?

Peter Styring answered on 17 Jun 2010:
Because they contain chlorophyll for photosynthesis (which is green). There can be other pigments present but these are not involved in photosynthesis but are usually for defence.

Chloroplasts are green because the contain something called chlorophyll for photosynthesis. Chlorophyll looks green because it absorbs light at specific wavelengths which are related to the colour green. I dont think they could be different colour because the molecular structure of chlorophyll makes it this colour..and if you changed the molecular structure it would no longer be chlorophyll and would not be able to photosynthesise!

cholroplasts contain a green pigment called chlorophyll, this makes it green. I wish plants were pink i love pink!

Pete commented on :
Chlorophyll is a chemical with a precise composition. The only way to change the colour would be to change the chemistry and then it wouldn’t be chlorophyll.
