The importance of photosynthesis to respiration of the human being is when the plant photosynthesis release oxygen and we breathe. If the habitat is contaminatedand we breathe makes us harm to health, that is the relationship between the diversity and health of the human being.
Oxygen is a product of the process of photosynthesis. on photosynthesis occur majortransformations: light energy is converted into chemical energy and inorganic matter into organic.
This process furofuranic is perhaps the one maintains the possibility due to our planet, becausethe metabolic waste that is released into the atmosphere is oxygen, a gas that breathes the majority of the living beings. Unlike most plants use light to produce food.
Special cells trap the lightfrom the sun and used to produce simple sugars and oxygen from carbon dioxide and water.
This process is known as photosynthesis: the formation of a compound with the help of the light, plants that usephotosynthesis contain an important pigment called chlorophyll which gives color to the green leaves.
The chemical structure of chlorophyll is similar to that of the hemoglobin in the blood. Theplants don't have a respiratory complex but small structures that favor the entrance and exit of the air; they are called stomata. These are found on the underside of the leaves of the plant and thelenticelas are in the stems and roots, and their role is similar to that of the stomata, with the proviso that borrower in the form of them does not eject oxygen to the outside world, unless it is of agreen stem, whose cells have chloroplasts.
Photosynthesis is important not only for the plants. Without it the world's animal life could never have evolved or could continue. The production of food,plants absorbs carbon dioxide from the atmosphere, an important factor to control the greenhouse effect, and release oxygen.
One way by which we found oxygen was when Joseph Priestley placed a lit...
