Answer:
Throughout the day plants manufacture oxygen via light-dependent photosynthesis by dividing water molecules.
In thylakoid membranes of chloroplasts, light-dependent processes occur and start with light energy absorption. This energy (including water and photosystems) is employed in the formation of ATP and NADPH, the reduced electron carrier necessary for the next photosynthesis phase. It releases oxygen.
Explanation:
At the same time, cellular respiration is used by plants to produce some of the carbon dioxide required for light-related sugar processes.
Cellular breathing is a chemical reaction of plants where glucose and oxygen are used to make carbon dioxide, water, and energy.
The plants create carbon dioxide at night, but not oxygen, due to cellular breathing.
At night there is no daylight, thus only cellular breathing happens.
During the day plants undergo a photosynthesis process, in which electrons are excited by light and electrons to begin flowing via Z-scheme. This electron flow causes PS II resonance and splitting of the water leading to the creation of O2 as a by-product. Cells in plants conduct simultaneous cell breathing to make ATP and produce CO2 during the interaction with the breathing cycle of cancer.
During the afternoon, no sunshine causes plants to photosynthesize and cells only breathe in order to make ATP carbon dioxide the by-product.
