    Cells contain a lot of organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, vacuole, nucleus, peroxisomes and so on... with this in mind what would guess then?

    Never underestimate your self :) And if you are in doubt, then answer the first idea that come to your mind, in many cases it is the right answer.

    Diffusion is a potential (a chemical potential) that is able to equalize concentration differences, and go from high concentration to low concentration, when the concentration of both sides is the same the net diffusion equals 0.

    Small cells have a high surface-area-to-volume ratio that makes them able to diffuse different molecules in or out more easy than big ones. The higher the surface-area-to-volume ratio the better diffusion can happen in a cell.

    Hmmm... okay can tell you the answer is A. ATP is also produced during anaerobic respiration. A plant can also do cellular respiration.

    It makes a very small amount of ATP in photosynthesis but it use that again during the Calvin cycle (uses 6 ATP) for 1 run.

    The light-independent reactions of photosynthesis A cannot occur if the light-dependent reactions are briefly inhibited. B involve the formation of carbon-carbon bonds. C only occur in the dark. D produce carbon dioxide and water.

    The light-independent reaction is the Calvin cycle. So if you know the calvin cycle you have the answer.
