Carbon dioxide is a waste product of photosynthesis and oxygen is a waste product of respiration
|
|
Carbon dioxide and oxygen are both waste products of photosynthesis
|
Detailed explanation-1: -Because plants don’t use oxygen, they release it as a waste product through the same pores they used to take in carbon dioxide. This is very helpful for humans and other animals who breathe the oxygen that plants release into the atmosphere.
Detailed explanation-2: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Detailed explanation-3: -Plants need to excrete excess carbon dioxides and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis.
Detailed explanation-4: -While the water and energy are useful to animal cells, they have no need for carbon dioxide. So it is breathed out of the lungs to remove it from the body. This is why carbon dioxide is considered a waste product in humans.
Detailed explanation-5: -Some of the oxygen produced in the process of photosynthesis is used in respiration by the leaf cells but the major portion of it is not required and it diffuses out into the atmosphere through the stomata. Therefore, it may be called a waste product of photosynthesis.
