Answer 2

The Process of Photosynthesis

Photosynthesis is a complex process that occurs in the chloroplasts of plant cells. It can be broken down into several key steps:

1. Absorption of Light Energy: - During photosynthesis, plants absorb light energy using pigments such as chlorophyll. - This light energy is used to power the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

2. Conversion of Carbon Dioxide and Water: - Carbon dioxide from the air enters the plant through small openings called stomata. - Water is absorbed by the plant's roots and transported to the leaves.

3. Production of Glucose and Oxygen: - In the presence of light, the absorbed carbon dioxide and water undergo a series of chemical reactions to produce glucose and oxygen. - The glucose serves as a source of energy for the plant, while the oxygen is released into the atmosphere as a byproduct.

4. Gas Exchange: - As a result of photosynthesis, oxygen is released into the atmosphere, contributing to the oxygen content in the air. - This process also involves the exchange of gases, with carbon dioxide being taken in and oxygen being released.

5. Role of Chloroplasts: - The chloroplasts within plant cells are the organelles responsible for carrying out the process of photosynthesis.

6. Overall Equation: - The overall chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

The process of photosynthesis is essential for the survival of plants and plays a crucial role in the Earth's ecosystem by producing oxygen and serving as the foundation of the food chain.
