Why does the lower epidemia have more stomata than the upper epidemia of a leaf

Biology
1 answer:
asambeis [7]3 years ago

The explanation lies in how the stomata works. They regulate any gasses that passes trough them. When the temperature is too hot, it will close to conserve water vapor but this will block CO2 coming in also. Therefor plants don't want to have their stomata closed all the time nor opened all the time. Sunlight hits the top surface of leaves. If many stomata were to be located on the top, the plant would loose much of its water and when the stomata closes to conserve water, it won't get as much CO2. Therefor for most plants, the stomata stay on the bottom where the temperature is a bit cooler. Also it is protected from the wind since wind can cause evaporation of water. I hope this Helps c:

denpristay [2]

Answer: CHANNEL PROTEINS provide openings in the plasma membrane for substances to flow through without changing structure, and CARRIER PROTEINS allow passage of substances through the plasma membrane after undergoing a subtle change in shape.

Explanation: They are described thus:

A channel protein is a protein that allows the transport of specific substances across a cell membrane.

Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell’s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.
