by oxygen in the atmosphere
During The Process Of Respiration, Plant Leaves Take In oxygen Through Their stomata.
There are a few functions that are performed during respiration in a plant but not in a human. One of these functions is breathing out oxygen.
both of which are released into the air during respiration. And during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis!
oxygen
What?? Plants don't take in oxygen. They take in carbon dioxide and make oxygen. Reread your textbook and you will be just fine.
Most of autotrophic plants get major amount of oxygen from photosynthesis. During night, when there is no photosynthesis, oxygen by plants is obtained from air However, the amount of oxygen released during photosynthesis by plants is manifold of their requirement for respiration.
Oxygen is required for cellular respiration in all cells. During photosynthesis oxygen gas is produced, this is used to produce glucose; oxygen is also then used during anaerobic respiration to break down the glucose to ATP. Oxygen for normal cellular respiration in other parts of the plant is supplied in solution via the root system.
Plant and animal cells wouldn't MAke ATP in cellular respiration.
sugar and oxygen
During photosynthesis glucose and oxygen are made by the plant. The glucose made is used by the plant as a form of food and the oxygen is discarded as a waste product.
Cellular respiration can be aerobic and anaerobic. Aerobic respiration requires oxygen, anaerobic respiration does not need oxygen.
Respiration can happen without sunlight, but photosynthesis cannot.
