Anatomy and Morphology of Plants
Specialized epidermal cells surrounding the guard cells are called as
Give only the functions of the following (a) Stomatal pore (b) Guard cell
a. Stomatal pore- It allows carbon dioxide to diffuse into leaf for photosynthesis. Water vapour and oxygen leave the leaf through the stomatal pores.
b. Guard cell- Guard cell facilitate gas exchange into and out of the plant by closing and opening the stomatal pore. It regulates the rate of transpiration.
Specialized epidermal cells surrounding the guard cells are called as

What causes the opening and closing of guard cells of stomata during transpiration?
Select the mismatched pair (A) Root hair Unicellular (B) Stem hair Multicellular (C) Trichomes Cause water loss (D) Guard cells Regulate opening and closing of stomata
Name the following. Cells that surround a stomatal pore
Stomata opens, because the guard cells have
When an oak leaf stoma opening move widely, the most likely process involved is
When stomata are opening; we observe which of the following changes in the guard cells?
The pH in the guard cells was observed when stomata were open, it ranges
