Leaves of green plants contain openings known as stomata. These are opened and closed by specialized cells that allow gases to b
e exchanged between the leaf and the outside environment. Which phrase best represents the flow of gases into and out of a leaf through stomata on a sunny day? a oxygen moves in; nitrogen moves out
b carbon dioxide moves in; oxygen moves out
c carbon dioxide and oxygen move in; ozone moves out
d water vapor and ozone move in; carbon dioxide moves out
The green leaves of the plant convert the available solar energy into chemical energy by the process of photosynthesis which s responsible for giving green pigment to the leaves.
The stomata present on the leaves are used for exchanging gases, they give out oxygen and take or absorb carbon gas. As carbon dioxide is exalted by animals and is taken by plants.
