What do plasmodesmata connect between adjacent plant cells?
ATheir cytoplasm, through the cell walls
BTheir nuclei, through the plasma membrane
CTheir vacuoles, through the middle lamella
DTheir chloroplasts, through the cytosol
Answer & Solution
Correct answer: A. Their cytoplasm, through the cell walls
1. Long stretches of neighbouring plant plasma membranes cannot touch, because a cell wall separates each cell from the next.
2. Plasmodesmata are numerous channels that pass between those cell walls.
3. They connect the cytoplasm of one cell with the cytoplasm of the next.
4. That connection enables materials to be transported from cell to cell and so throughout the plant.
5. The link is cytoplasm to cytoplasm, through the walls.
