Photosynthesis
Introduction
Photosynthesis is a fundamental process by which green plants, algae, and some bacteria convert light energy into chemical energy. This process takes place in the chloroplasts of plant cells, where sunlight, water, and carbon dioxide are transformed into glucose and oxygen.
Importance of Photosynthesis
Photosynthesis plays a crucial role in maintaining the balance of oxygen and carbon dioxide in the atmosphere. It is also the primary source of energy for all living organisms, forming the base of the food chain.
Process of Photosynthesis
The process can be divided into two main stages:
- Light-dependent reactions: These reactions occur in the thylakoid membranes of the chloroplast, where sunlight is absorbed, water is split, and oxygen is released.
- Calvin Cycle: In this stage, carbon dioxide is fixed and converted into glucose through a series of reactions in the stroma of the chloroplast.
