How do I prove that a leaf contains many tiny openings called stomata?

Answer 1

they are easily seen under a microscope. As far as i know, without physiological equipment, it's the only way to see them...

Answer 2

You can do this even without a microscope. As u know that stomata are meant for exchange of gases from atmosphere and transpiration ( expelling excess water ), u can do it as follows :

Take a healthy, potted plant and cover one of its leaves with a transparent plastic sheet. Leave the setup for a day or two and then observe. You will observe that the leaf would wilt and die. The reason is that the leaf dies due to lack of respiration. You can also observe tiny droplets of water on the under side of the plastic sheet. This proves loss of water from leaf. Hence, there must be certain openings on surface of leaf for gaseous exchange and transpiration, which are nothing but the stomata.

Note: The transparent sheet is used to allow exposure of leaf to sunlight.

Answer 3

You can always prove what you can't see by observing what the part does.

Cover half a plant leaf with Vasoline both top and bottom and on the other side leave it clear of vasoline. Let it sit for a week and when you come back the side with vasoline should be yellowish.

This is because CO2 enters through the stomata and is necessary for photosynthesis. when you block the holes or stomata this prevents CO2 form entering and photosynthesis from taking place.

Answer 4

Magnify the leaf and look for yourself.

Answer 5

try different types of leaves. you will be able to see them with naked eyes in one of them. or use some lens. try leaf of lemon you can definitely see in it.

Answer 6

Why to prove ??
Its proven
