Title: Why aren't there any chloroplasts presented in the onion cell?
Post by: HKL4EVER on 14/10/2009 01:11:47

i am doing my biology homework and i am observing an Onion Cell. I just realized there weren't any chloroplasts shown in the onion. and i want to know why isn't presented? i know that chloroplasts are organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis. Chloroplasts capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH through a complex set of processes called photosynthesis. So can anyone or anybody please help me. Thank you for your time and need (:

Doesn't an onion grow under ground, where there's no light?
No light = no need for chloroplasts.

PS: The parts of onions that do grow above ground will have chloroplasts
