NEET 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 apoplast pathway, water is transported from root hair to xylem through the cell wall of intervening cells. Apoplastic water movement beyond the cortex is blocked by the Casparian strip of endodermal cells. Hence, the symplastic route is utilised to deliver water and ions beyond the cortex.

Detailed explanation-3: -So, the correct option is ‘plasmodesmata’.

Detailed explanation-4: -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-5: -Plasmodesmata connect neighbouring cells throughout a plant to establish the symplast. Plasmodesmata establish an interconnected cytoplasm called the symplast, through which metabolites, proteins, and RNAs are exchanged between cells, tissues, and organs.
