Question What is photosynthesis
Answers
Answer:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
Equation
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Components
In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants. GA3P and oxygen are products.
Steps
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast:
(1) absorption of light,
(2) electron transport leading to the reduction of NADP+ to NADPH,
(3) generation of ATP, and
(4) conversion of CO2 into carbohydrates (carbon fixation).
Importance
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die
