Photosynthesis is the process by which plants convert sunlight into energy from "summary" of NCERT Exemplar Problems-Solutions BIOLOGY class 12th by Arihant Experts
Photosynthesis is a vital process that occurs in plants, allowing them to harness energy from sunlight. This energy is crucial for the survival and growth of plants. The process of photosynthesis involves the conversion of light energy into chemical energy, which is then stored in the form of glucose. This glucose acts as a source of energy for plants, enabling them to carry out various metabolic activities. During photosynthesis, plants use chlorophyll - a green pigment found in the chloroplasts of plant cells - to capture sunlight. The chlorophyll absorbs light energy and converts it into chemical energy through a series of complex biochemical reactions. This energy is then used to convert carbon dioxide and water into glucose and oxygen. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct, contributing to the oxygen supply in the environment. The overall equation for photosynthesis can be represented as follows: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. This equation illustrates the conversion of carbon dioxide and water into glucose and oxygen, driven by light energy. The glucose produced serves as a source of food and energy for plants, supporting their growth and development. Photosynthesis plays a crucial role in the ecosystem, as it is the primary source of energy for plants. Through photosynthesis, plants are able to produce their own food, which in turn sustains other living organisms in the food chain. Additionally, photosynthesis is vital for maintaining the balance of gases in the atmosphere, as it helps to remove carbon dioxide and release oxygen.- Photosynthesis is a fundamental process that enables plants to convert sunlight into energy. This energy is essential for the survival and growth of plants, as well as for supporting life on Earth. By understanding the intricate process of photosynthesis, we can appreciate the significance of plants in maintaining the ecological balance of our planet.
