Photosynthesis



Photosynthesis: food production by plants

Which is

Photosynthesis is a process carried out by plants to produce their own food. Simply put, we can understand that the plant removes carbon dioxide from the air and energy from the sun.

Process

Through this process, the plant produces its own food consisting essentially of glucose. As the plant produces glucose, it eliminates oxygen.

Glucose is used by the plant to perform its metabolic functions, ie, it is its main fuel, without it, it would be impossible to maintain its vital functions.

The process of glucose formation occurs through chemical reaction, and this is only possible due to the transformation of solar energy into chemical energy.

Importance of Photosynthesis

Without photosynthesis, there would be no life on our planet, because it is through it that the whole food chain begins. Hence the great importance of plants, green vegetables and some other organisms.

In addition, as we have seen, as the plant produces glucose it eliminates oxygen, and without oxygen it is impossible to survive.

Consequences of photosynthesis for life and for the planet

Photosynthesis has profound consequences for the planet and life, being responsible for the emergence of aerobic respiration and the dominance of aerobic bacteria.

And as a result of aerobic respiration, which is more energy efficient, eukaryotes emerged, initially unicellular protists.

The earth's atmosphere has undergone changes in its composition through the release of molecular oxygen through photosynthesis.
