Which of the following statements about plant anatomy is incorrect?

The incorrect statement is "In transpiration, liquids are expelled out." This statement is not entirely accurate because, during transpiration, only water vapor is expelled out through the stomata of the leaves. Transpiration is the process by which water is lost from the leaves of plants in the form of water vapor. This loss of water vapor creates a negative pressure or tension in the plant, which in turn creates a "pull" or suction force that helps to draw up water and minerals from the roots to the leaves.

"Transpiration pull brings up the water through roots" is a correct statement.

"Subsidiary cells encircle the guard cells" is a correct statement. Subsidiary cells are specialized cells that surround the guard cells and help to regulate their function in controlling the opening and closing of stomata.

"Guard cells surround the stomatal pore" is also a correct statement. Guard cells are specialized cells that surround the stomatal pore and help to regulate the exchange of gases and water vapor between the plant and the environment.
