1.	Guard cells are small in size and are kidney shaped in outline. Give reasons.
Answer» Because of their small size, guard cells are rapidly influenced by turgor changes. Because of their kidney shaped outline, they remain joined at their ends. This concave-convex curvature of the two guard cells can be varied easily and this further facilitates the stomatal pore to open and close easily.
