Question

Identify the diagram given. Define the process.

Answer 1

• The picture demonstrates the process of photosynthesis.
• It is the process by which plants utilize the sunlight, water and carbon dioxide to synthesise food (glucose).
• Carbon dioxide present in the atmosphere passes through small pores on leaves called stomata.
• Water absorbed by the roots passes through the vessels in the stem to the leaves.
• Sunlight is absorbed by the pigment called chlorophyll present in the chloroplast of leaves.
• Solar energy is converted to chemical energy which splits the water molecules to give hydrogen and oxygen.
• Oxygen is released from the stomata to the atmosphere as a waste product.
• Some glucose is used to provide energy to plants for growth and development.
• Rest of the food is stored in the leaves, fruits, roots of plants.
