AP BIOLOGY

Detailed explanation-1: -The symplastic pathway: It provides the movement of water from one cell to another cell by plasmodesmata. Symplast is the inner side of the plasma membrane.

Detailed explanation-2: -In the active absorption, the water first enters the cell sap and passes from one cell to another. This type of movement where protoplasm is involved is called symplast. In passive absorption, water moves through the apoplast of the root. The apoplast path includes the cell wall and intercellular spaces.

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