What is the function of stomata in plants? a. to transport materials from the soil to the leaves b. to absorb light energy from the sun c. to allow gas exchange between the environment and the inside of leaves d. to transport materials from the leaves to the soil

c. To allow gas exchange between the environment and the inside of leaves.

Explanation:

Stomata are small openings on the surface of the leaves of green plant that mediate the exchange of gases between the leaf and atmosphere.The stomatal aperture is Guarded by elongated bean shaped cells called guard cell. In grasses the guard cells are dumbell shaped. The turgidity and flaccidity of the guard cells control the opening and closing of stomata andthus regulate the exchange of gases during day and night.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
