Answer the following question given this paragraph: A third difference between plant and animal cells is that plants have several kinds of organelles called plastids . And there are several different kinds of plastids in plant cells. For example, Chloroplasts are needed for photosynthesis, leucoplasts can store starch or oil, and brightly colored chromoplasts give some flowers and fruits their yellow, orange, or red color. It is the presence of chloroplasts and the ability to photosynthesize, that is one of the defining features of a plant. No animal or fungi can photosynthesize, and only some protists are able to. The photosynthetic protists are the plant-like protists, represented mainly by the unicellular algae. Q: Chloroplasts, leucoplasts and chromoplasts are found in what type of cells? A:

Choices:
(A). nitrogen cells
(B). animal cells
(C). man-made cells
(D). plant cells
The answer is:
(D).
