The air spaces occur in Spongy mesophyll tissue.There are large spaces in a leaf because it is for storing water and carbon dioxide which will be used for photosynthesis. The large air spaces are usually found in the spongy layer of the mesophyll. The arrangement of this spongy mesophyll facilitates the movement of gases through the mesophyll. Directly beneath each stomate at the leaf surface there is usually a small air space, called a stomatal chamber, where no mesophyll cells are present. This also aids in gas exchange.

Answer: Option C.
if resistance increases, flow decreases.
Explanation:
if resistance increases, flow decreases describe Poiseuille's law because it explain the relationship between fluid flow and the viscosity of the fluid, length and width of the turning. The law describe fluid flow is related to length and radius of tubing and viscosity. Increase in resistance will result in decrease in flow rate because flow and resistance are reciprocally related in one way or the other.
