$\sf\blue{What \: is \: photosynthesis?}$

$\huge\underbrace\pink{\dag Answer \dag}$

Photosynthesis takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere. Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.

$\bold \star\green{\underline{\boxed{Formula}}}\star$

6CO2 + 6H2O → C6H12O6 + 6O2.

$\bold \star\green{\underline{\boxed{Purpose}}}\star$

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

$\bold \star\green{\underline{\boxed{Importance}}}\star$

Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

Answer 2

● Photosynthesis is the process by which living plant cells which contains chlorophyll, produce food substances like glucose and starch from carbon dioxide and water by using light energy.

● It provides food for all living beings including animals and humans.

● It provides us oxygen to breathe in by releasing oxygen into the atmosphere.

Photosynthesis can occur in two phases

1. Light Reaction
2. Dark Reaction

● Light reaction traps the energy by using chlorophyll and use that energy in splitting water molecules into hydrogen and oxygen which is called photolysis.

● Dark reaction transfer the hydrogen from NADPH through a series of chemical reactions to combine with carbon dioxide to produce glucose by using energy from ATP
