Chapter 28, Problem 12SQ
Summary Introduction
Introduction: Guard cells are the cells that are present above and below surfaces of leaves. It controls the transfer of gaseous and water molecules during the transpiration. Guard cell contains a small opening structure called as stomata through which the molecules escape.
