Question

1. What structures regulate water loss and CO2 absorption by a leaf?

Answer 1

Hi Rosalina Martha Kononenko,

The structure on the leaf is called a stoma (plural stomata).  The parts of this structure include two specialized guard cells which open and close the pore to regulate gases entering and exiting and transpiration (water vapor release).

See the link below for a diagram and more info.

I hope this helps.
