FAQs on Parts of Plants Important Questions - Class 3 Science

1. What are the main parts of a plant and their functions?
Ans. The main parts of a plant include roots, stems, leaves, flowers, and fruits. The roots anchor the plant in the soil and absorb water and nutrients. The stem supports the plant and transports water and nutrients. Leaves are where photosynthesis occurs to produce food for the plant. Flowers are the reproductive part of the plant, and fruits contain seeds for reproduction.
2. How do roots help plants survive?
Ans. Roots help plants survive by anchoring them in the soil, absorbing water and nutrients, storing food, and providing support for the plant. They also help prevent soil erosion and compete with other plants for resources.
3. Why are leaves important for plants?
Ans. Leaves are important for plants because they are where photosynthesis occurs. Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce food in the form of glucose. Leaves also help regulate water loss and exchange gases with the environment.
4. What is the role of flowers in plants?
Ans. Flowers are the reproductive part of plants. They attract pollinators like bees, butterflies, and birds to transfer pollen from one flower to another for fertilization. Once fertilized, flowers develop into fruits that contain seeds for new plant growth.
5. How do stems support plants?
Ans. Stems support plants by providing structure and stability. They also transport water and nutrients from the roots to the leaves and other parts of the plant. Stems can also store food and water for the plant's growth and survival.
