Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
water movement through cellulose cell wall without entering protoplast of root cells is called
A
symplast pathway
B
vacuolar pathway
C
apoplast pathway
D
cellulose pathway
Explanation: 

Detailed explanation-1: -In apoplast pathway water moves through cell wall without crossing any membrane.So, the correct option is ‘apoplast pathway’

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: -The apoplast is the route the water moves through the cell walls and intercellular space of the root cortex. In the symplastic route, the water moves through the protoplasts of the root cortex. The apoplast route is the fully permeable route in which the water movement occurs in passive diffusion.

Detailed explanation-4: -The symplast is the pathway in which the water molecules moves through the plasmodesmata region in the cells. The symplast is the living region present between two cells which connects one cell with the other. The apoplast pathway is the path in which the water is moving between the intercellular spaces.

Detailed explanation-5: -The apoplastic movement of water occurs exclusively through the intercellular spaces and the walls of the cells, depending on the water gradient. Q. Assertion :During apoplastic movement of water, water travels through the cells and their cytoplasm.
