Name the elements that are required for Photosynthesis.

Correct option is B

​The correct answer is (b)Carbon dioxide, water and sunlight

Explanation:

Photosynthesis is the process by which plants, algae, and certain bacteria convert light energy into chemical energy stored in glucose. The three key elements required for photosynthesis are carbon dioxide (CO₂), water (H₂O), and sunlight.

• Carbon dioxide is absorbed from the atmosphere through the plant's stomata.
• Water is absorbed by the plant's roots from the soil.
• Sunlight is absorbed by the chlorophyll in the plant’s cells, which is responsible for capturing light energy and converting it into chemical energy.

The overall reaction is:

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

This process takes place in the chloroplasts of plant cells.

Information Booster:

• Chlorophyll: The green pigment in plants, which plays a key role in capturing sunlight and initiating the photosynthetic process.
• Photosynthesis Stages:
• Light-dependent reactions: Occur in the thylakoid membranes of the chloroplasts, where sunlight is absorbed and converted into chemical energy in the form of ATP and NADPH.
• Calvin cycle (light-independent reactions): Occur in the stroma of the chloroplast, where carbon dioxide is fixed and converted into glucose.
• Importance of Photosynthesis:
• It produces oxygen as a by-product, which is essential for the survival of most living organisms on Earth.
• It forms the foundation of the food chain by providing energy in the form of glucose for plants and herbivores.
