biology question #1632

Nameless, a 14 year old female from Internet asks on October 17, 2003,

Q:

Chloroplasts, which help give the cell energy using photosynthesis, also make the cell green, right? So why is it that not all plants are green or not all parts of a plant are green??

Not all parts of a plant have chloroplasts. Chloroplasts, and hence green cholorphyl molecules are mainly concentrated in the leaves. That's why leaves are green and, for many plants, the rest of the plant is not green.
