There are small openings on the lower surface of the leaves. These pores are called stomata. These openings are surrounded with guard cells.
Stomata helps in the transpiration of water, i.e., the loss of excess water from the plant. Loss of water from the stomata creates an upward pull, i.e., suction pull which helps in absorption of water from the roots. Stomata help in exchange of gases.

Why does chameleon change its colour?

Posted by Tanya Garg 7 years, 2 months ago

Yogita Ingle 7 years, 2 months ago

A chameleon changes its color to adjust its body temperature to that of the outside temperature. A cold chameleon will turn dark to absorb more heat, while a hot chameleon will turn lighter in shade in order to reflect the heat from its body. Also the change in color in a chameleon can indicate its mood. An angry chameleon will have a darker color, whereas a chameleon in a relaxed mood will have a lighter color.
