The bean shaped cells which enclose stomatal pore are calledGuard cellsSubsidiary cellsStomatal apertureCuticle

A cell in the outer covering of a plant's body that can change shape in order to open or close a pore

Tiny pores are found on the surface of the leaves of plants. These pores are calledstomata. These stomata surrounded by the kidney shaped guard cells provide manyvital functions to the plants.Which of the following functions is not served by the stomata for the plants?(A) Exchange of gases, particularly CO2 and O2, with atmosphere(B) Loss of water in the form of vapours during transpiration(C) Helps to create pressure for the water to rise upward, by its process oftranspiration.

All of the following are the features of guard cells except These are the only epidermal cells that contain chloroplastsGuard cells can undergo rapid turgor changesThe opening and closing of the stomatal pore is a function of guard cellsTheir outer and lateral walls are comparatively thicker than inner wall

The type of epithelium that consists of a superficial layer of columnar cells overlying several layers of cuboidal cells is called columnar epithelium.

Which part of a plant cell helps maintain its shape?
