Animal cells do not contain chlorophyll as they do not need photosynthesis to generate energy.  A plant is unable to turn the sun's rays into a food source without photosynthesis.

Answer:the correct option is B

Why viruses are not alive
nevsk [136]
Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
