I need the answer asap please... explain the sugar translocation in the plant starting with the leaf cell
(source cell) to the root cell (sink cell).

I think this is it.. Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements.

Explanation:

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

it depends on how much it could carry.
