Have you ever wondered how plants make their own food? Just like we have kitchens in our homes to cook food, plants have leaves – the food factory of plants! Yes, you read it right. Leaves are the food factories of plants because they make food through a special process called photosynthesis.
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 Plant 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.
The food factory of Plant worksheets
In this lesson, we will explore why leaves are called the food factory of plants, how plants make food, and why green plants are important for all living beings. This topic is covered in detail in Class 4 EVS and Science curriculum.

The Food factory of Plants Class 4 Questions and Answers
Q1. Why is the Leaf Called the Food Factory of the Plant?
Ans. Leaves are rich in a green pigment called chlorophyll, which helps plants capture sunlight. Using sunlight, water, and carbon dioxide, leaves make food in the form of glucose. This process is called photosynthesis. That’s why leaves are the food factories of plants.
Q2. Why is the leaf called the kitchen of the plant?
Ans. Because just like a kitchen is used to prepare food at home, the leaf is the kitchen of the plant, where food is prepared using natural ingredients – sunlight, air, and water!
Q3. What is photosynthesis?
Ans. 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.
Q4. What is chlorophyll?
Ans. 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.
Q5. What is Stomata?
Ans. 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.
