Question

I am not sure if i understand this thing in the right way. Is that the casparian strip in the cell wall of the endodermis cell layer work by making the water diffuse into the cell and make the cell hypotonic to the surrounding so the water is easier to diffuse into the xylem?

Answer 1

first thing caperian trip not allows water to diffuse dats y from that the water adopt symplast pathway

Answer 2

*casperian

Answer 3

em why the plant make the water flow in the symplast pathway?

Answer 4

ok wen water enter in roots der is a two way to reach xylem dat i apoplast and symplast here apoplast is the fastest way so mostly water moves by diffusing and rest go as symplast way

Answer 5

but we casperian strips came the water change its path and move in symplast way

Answer 6

The Casparian strip does indeed force water transport to occur through the cell, but this is potentially slower and less efficient than allowing apoplastic transport through the cell wall -- apoplastic transport is passive, symplastic is active. The main advantage that the plant gets from symplastic transport is the ability to control the intake of water and other substances. This means that water can be forced into the xylem through these endodermis cells (through the transport of mineral ions to create an osmotic gradient, I believe), but it also means that the plant can block harmful solutes from entering the root.
