Answer 6

In that case I can help you. For the first question, you know that you're looking for something in plant cells. Mitochondria are only in animal cells, so that's not it. And in this case, it's just a matter of knowing, memorizing, whatever you want to call it that light energy is absorbed by chlorophyll.
