Leaves are indeed the food factory of plants, and they play a very important role in the process of photosynthesis, which is how plants make their own food.
Photosynthesis is a magical process that occurs in the plant world. It is the process by which plants use sunlight, carbon dioxide, and water to create their own food.
The chapter Food factory of Plants for class 4 delves into the science behind this process and understand the role of chlorophyll, the green pigment found in leaves, in converting light energy into chemical energy.
We will also have a closer look at the basic structure of leaves, which is designed specially for the process of photosynthesis.

Food factory of Plants Class 4 Questions and Answers
Why leaves are called food factory of plants?
Leaves are the primary site of photosynthesis in plants. They capture light energy from the sun and convert in to energy usable for plants.
Leaves have specialized cells called chloroplasts that contain chlorophyll, the green pigment responsible for absorbing light energy. Chlorophyll is essential for photosynthesis, as it captures the energy from sunlight and converts it into chemical energy.
What is photosynthesis?
During photosynthesis, the chloroplasts in the leaves use energy from the sun, along with carbon dioxide from the air and water from the soil, to create glucose, which is a type of sugar. The glucose is then used by the plant as food, and oxygen is released into the air as a by-product.
What is chlorophyll?
Leaves are specifically designed to carry out photosynthesis efficiently. They have a large surface area, which allows them to absorb more sunlight, and they contain chlorophyll, a green pigment that absorbs the energy from the sun’s light.
What is Stomata?
Leaves also have tiny pores called stomata, which allow carbon dioxide to enter the plant and oxygen to exit. Stomata can also regulate the amount of water that enters and exits the plant, helping to prevent dehydration.
