IgorLugansk [536]

Sugars pass from cell to cell in the leaf starting in the _______ of the mesophyll; they move through the _______ of other cells
Scorpion4ik [409]

Sugars pass from cell to cell in the leaf starting in the symplast of the mesophyll; they move through the symplast or apoplast of other cells and finally pass into the symplast of the sieve tube element

In symplastic pathway the sugar will move through the cytoplasm of the cell and pass on to the other cell through the plasmodesmata.

In apoplastic pathway the sugar will move through the cell wall and intercellular spaces and does not cross the cell membrane.

When the sugar are synthesized by the leaves first it will move through the symplast of the mesophyll cells. Then sugar will be travelling either through symplastic or apoplastic pathway in other cells and pass through the sieve tube elements in symplastic pathway
