Which of the Following Features of Plant Cells Allows for Symplastic

Question

Which of the following features of plant cells allows for symplastic movement of water?
A) cytoskeleton
B) aquaporins
C) porous cell walls
D) plasmodesmata
E) large central vacuole

Accepted Answer

Plasmodesmata are channels that allow for the movement of water and other substances between plant cells, making it possible for water to move through the cytoplasm from one cell to another, a process known as symplastic movement. The cytoskeleton helps maintain cell shape and is not directly involved in water movement, while aquaporins are protein channels that facilitate the movement of water across cell membranes, but not between cells. Porous cell walls and a large central vacuole may aid in water storage, but do not allow for symplastic movement.
