What side of a plant leaf takes in carbon dioxide?
The definition of a leaf is a part of a plant or tree attached to the stem or branches.
Leaves contain chloroplasts, in which photosynthesis occurs.
When the stomata are shut (guard cells lack water), there is no space for gasses to move in and out of the leaf, limiting the rate of photosynthesis (as CO
Printout A plant is a member of the kingdom Plantae, a living organism that utilizes photosynthesis, a process in which energy from sunlight is converted to chemical energy (food).
A summary of the inputs and outputs of photosynthesis is:
Origin of leafMiddle English lefe from Old English leaf, akin to Dutch loof, German laub from Indo-European base an unverified form leubh-, to peel off, pull off from source Lithuanian lupù, to skin, pare off
An example of a leaf is the part of the tree that is green in the summer and may change colors and fall off of the tree before the start of winter.

This process uses the sugars produced by photosynthesis and converts them into energy which the plant can use (this energy is contained within molecules called ATP – adenosine triphosphate). Oxygen is used in these reactions and, as well as charged up ATP molecules, the process releases water and carbon dioxide.
Plants absorb water through their roots, and carbon dioxide through their leaves. Some glucose is used for respiration, while some is converted into insoluble for storage. The stored starch can later be turned back into glucose and used in respiration. Oxygen is released as a by-product of photosynthesis.
