The word photosynthesis comes from the Greek and is formed by the term photo, which is equivalent to light, and by synthesis, which means formation of compounds.
In the field of photosynthesis biology refers to the ability of plants to transform the energy light solar energy chemistry . This process allows plants to generate their own food.
Without this process, life on the planet would not be possible.
The main idea of photosynthesis and process development
Plants absorb carbon dioxide (CO2), more water (H20), more photons or sunlight. With these elements they can generate carbohydrates and oxygen. In this sense, carbohydrates provide energy to animals and oxygen is essential for the breathing of living beings. Photosynthesis is a type of anabolic chemical reaction , meaning that substances are created or synthesized from others. Photosynthesis
The first part of the process is light absorption . In this sense, sunlight is captured by the chlorophyll of plants. Plants obtain carbon dioxide from the stroma found in the leaves and stem. Plants absorb water in two ways: through the roots that are in contact with the soil or through the stroma in the form of water vapor. Therefore, in photosynthesis there are two different steps: one that depends on light and another that is independent . In the first, energy molecules (such as ATP) and oxygen are generated. In the second, the ATP produced is used in the formation of glucose.
The photosynthesis process allows us to understand how plants feed and how oxygen is produced in the atmosphere
Like any other living thing, plants need to feed to live. However, unlike animals, they do not feed on other animals, but through light, water and minerals. Plants produce their own food, the sap produced is basically formed by glucose. Photosynthesis
Plant nutrition requires three elements: water, mineral salts and carbon dioxide. Regarding the feeding process, it consists of four phases:
1) in the first, plants absorb water and mineral salts found in the soil through their roots;
2) Once water and mineral salts are absorbed, plants create a raw sap that circulates from woody tubes to leaves;
3) in the leaves are small pores through which carbon dioxide from the air enters;
4) this gas mixes with the raw sap and combined with sunlight it transforms into an elaborate sap, which allows the plant to be fed as a whole.
Throughout this process, plants expel the oxygen released into the atmosphere , making life possible for all living beings.
