AP BIOLOGY

Detailed explanation-1: -In the symplastic pathway, the movement of water is in between the cytoplasm and the vacuoles through the plasma membranes and plasmodesmata and beyond the cortex of plant cells. The pathway is slower when compared to the apoplastic pathway.

Detailed explanation-2: -In symplast pathway, water passes from cell to cell through their protoplasm. It does not enter cell vacuoles. The cytoplasm of the adjacent cells are connected through plasmodesmata. Symplastic movement is aided by cytoplasmic streaming of individual cells.

Detailed explanation-3: -Water can move between cells and through the cell walls and intercellular spaces in the apoplast pathway (apoplastic route) or between adjacent cytoplasms through plasmodesmata in the symplast pathway (symplastic route).

Detailed explanation-4: -In symplastic pathway, water enters cells through plasmodesmata and travels through the cytoplasm.

Detailed explanation-5: -So, the correct option is ‘plasmodesmata’.
