What are the functions of the air spaces near the lower surface of the leaf?

OpenStudy (praetorian.10):

Spongy mesophyll tissue dude

OpenStudy (praetorian.10):

short answer is storing water and CO2

OpenStudy (arwen0222):

Thank you very much!

OpenStudy (praetorian.10):

long answer is: 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.

OpenStudy (praetorian.10):

i copy and pasted that last bit

OpenStudy (praetorian.10):

everything about plants revolves around photosynthesis

OpenStudy (praetorian.10):

its safe to say that any aspect of a plant is used for this purpose

OpenStudy (praetorian.10):

like humans, everything about us is engineered for survival

OpenStudy (praetorian.10):

otherwise it would be analogous

OpenStudy (praetorian.10):

unnecessary and dormant

OpenStudy (praetorian.10):

so bye bye with it :)
