Read the following statements and find out the incorrect statement.

Easy

A

Stomata are involved in exchange of gases as well as loss of water in the form of vapour during transpiration.
B

When guard cells have high turgor pressure, the stomates are opened and when the turgor pressure is less or negligible the stomates are closed.
C

Loss of water in the form of liquid or droplets through hydathodes is called Guttation.
D

Transport of water through xylem from root to leaf is mainly due to development of root pressure.

Solution

Ascent of sap or transport of water through xylem is mainly due to transpiration pull developed in the leaf as result of transpiratory loss of water from mesophyll cells. Root pressure may aid in modest push of water column in the xylem and re-establishing the water link in xylem which is lost due to excessive tensions. Root pressure also helps in guttation.
