for the exchange of gases (carbon dioxide and oxygen)
The structure of a plant that regulates the intake of the substances needed for photosynthesis to occur is the stomates. Stomates are microscopic round openings on the back of a leaf. around the stomates are guards that kind of act as lips controlling how far the stomates need to be opened.
There are no stomates on the stem of the plant.
cuz yoo
Oxygen
To allow for the exchange of gases in and out of the plant.
Stomates =] ♥
the stomata's allows the exchange of carbon dioxide or CO2
true :)
Stomates are responsible for most of the gas exchange that occurs in a plant.
The stomata remain wide open
Gaseous exchange and evaporation of water vapour
The stomates of a leaf are located in the epidermis, which is the outermost layer of leaf tissue. Specifically, they are often found within the lower epidermis to minimize water loss while still allowing for gas exchange. The stomatal openings are surrounded by guard cells that regulate their opening and closing.
