A
Apoplast

B
Symplast

C
Cross connections

D
Plastidome

Solution

The correct option is B Symplast
Symplast pathway is the pathway formed by the system of interconnected protoplasts of different cells. Neighbouring cells are connected through cytoplasmic strands extend through plasmodesmata. During symplastic movement, the water travels through the cells-their cytoplasm; intercellular movement is through plasmodesmata. Water has to enter the cells through the cell membrane, hence movement is relatively slower. Movement is down a potential gradient. Symplastic movement may be aided by cytoplasmic streaming. It can be seen in cells of Hydrilla leaf.
