what is photosynthesis give brief answer
Answers
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Photosynthesis is a metabolic process in plants, algae, cyanobacteria, some protists, converting light energy into chemical energy that is used by a cell to produce food.
Process Of Photosynthesis
At the cellular level, the photosynthesis process takes place in cell organelles called chloroplasts. These organelles contain a green-coloured pigment called chlorophyll, which is responsible for the characteristic green colouration of the leaves.
As already stated, photosynthesis occurs in the leaves and the specialized cell organelles responsible for this process is called the chloroplast. Structurally, a leaf comprises a petiole, epidermis and a lamina. The lamina is used for absorption of sunlight and carbon dioxide during photosynthesis.
The Equation for Photosynthesis
The photosynthesis equation is written as: 6H2O + 6CO2 → C6H12O6 + 6O2 and is explained in words as the reaction of six water molecules with six carbon dioxide molecules yielding one glucose molecule and six oxygen molecules. Note that one oxygen molecule contains a pair of oxygen atoms.
