Photosynthesis makes oxygen but cellular respiration takes that oxygen so how is there oxygen in the air?

Explanation:

in day time photo in photosynthesis make Oxygen and that oxygen is used by cellular respiration which produces which releases carbon dioxide in written in return so it is Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (. The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
