Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy, usually from the sun, into chemical energy that can be used to fuel the organism's activities. In simpler terms, during photosynthesis, plants take in carbon dioxide (CO2) from the air and water (H2O) from the soil, and using sunlight as energy, they produce glucose (a type of sugar) and oxygen (O2). This process is fundamental for Class 10 science as it plays a crucial role in the Earth's ecosystem, notably in energy transfer and oxygen production.
FAQs & Answers
- Why is photosynthesis important for plants? Photosynthesis is important because it enables plants to produce glucose, which serves as their primary energy source, and releases oxygen vital for many living organisms.
- What are the main raw materials required for photosynthesis? The main raw materials for photosynthesis are carbon dioxide from the air, water from the soil, and energy from sunlight.
- How does photosynthesis affect the Earth's ecosystem? Photosynthesis contributes to oxygen production and forms the base of the food chain by converting sunlight into chemical energy, supporting nearly all life on Earth.
