Do both animal and plant cells have chloroplasts? Explain why or why not.
A. No, not all. Chloroplasts contain a green pigment called chlorophyll. All plant cells have chloroplasts, but only some animal cells, such as green frogs, have chloroplasts.
B. Yes. Chloroplasts contain a green pigment called chlorophyll. All plant cells have chloroplasts, but only some animal cells, such as green frogs, have chloroplasts.
C. Yes. Chloroplasts transport important molecules for the cell to use. All cells need to be able to harness energy for food and chloroplasts get their name from chlorophyll, which is a green pigment used for photosynthesis giving plants their food. They are named chloroplasts because they were discovered in plant cells before they were discovered in animal cells.
D. No. Chloroplasts contain chlorophyll, which plants use to absorb light energy as part of photosynthesis. Animals do not perform photosynthesis, so they do not have chloroplasts.
