Where does photosynthesis occur in these plants?

Question

Where does photosynthesis occur in onions and potatoes?What is the evolutionary significance of storing their starches underground? (2 big things)

Answer 1

Photosynthesis occurs in the aboveground parts of onions and potatoes: leaves of onions and leaves/stems of potatoes.

Storing starches underground protects the plant's food stores from animals that are looking for food. It's just a bit harder for these consumers to get to the plant's food. Also, the onion is a biennial -- the second year plant will use the stored food to grow. Potatoes are tubers which are specialized underground stems. The eyes on the potatoes are buds that can grow the next year if they are left in place -- the starch in the potato gives it food to start growing.

Answer 2

Photosynthesis Occur

Answer 3

Photosynthesis occurs in the leaves. Starch is stored food.

Answer 4

onions are bulbs underground and potatoes are considered to be a root, the actual photosynthesis happening is on the plant above the ground in which the potato/onion grows with

Answer 5

photosynthesis occurs in green parts,which contain chlorophill,by taking sun light,waterand minerals from the earth.
then the prepared food can be stored either in leaves or bulbs.
onnion and potat both are bulbs.
i think it will be the correct answer 4 ur question otherwise sorry for wasting ur time.

Answer 6

Most of the Plants do photosynthesys in leaves only.very rare case plants use stem.

Answer 7

if you want the whole answer to the photosynthesis question then just google the Krebs cycle. i could tell you it here but itd take a whole page. as for why they store the carbs underground, its just one of lifes little mysteries as far as im concerned

Answer 8

the energy is absorbed through the leaves then taken via the stem to the roots where that energy is used, then taken back out the leaves, becuase it is now oxygen. now u noe y humans need plants

Answer 9

james is correct
