Assertion (A) : In symplastic path water movement is relatively slower
Reason (R) : In symplastic path water has to enter the cell through cell membrane

Assertion (A) is true. In the symplastic pathway, water and solutes move through the living cells of the plant, typically by traveling through plasmodesmata, which are small channels that connect the cytoplasm of neighboring plant cells.

The reason for the slower movement in the symplastic pathway is that water must enter the living cells through the cell membrane, and this movement through the cell is generally slower compared to the apoplastic pathway, where water can move through the cell walls and intercellular spaces, bypassing the cell membranes.

So, the assertion and the reason are logically related, and both are accurate. The symplastic pathway does involve a slower movement of water compared to the apoplastic pathway, in part because it requires the water to enter the cells through the cell membranes.
