FAQs on Mind Map: Plant Life - Science Class 5

1. What are the main parts of a plant and their functions?
Ans. The main parts of a plant include the roots, stem, leaves, flowers, and fruits. Roots anchor the plant in the soil and absorb water and nutrients. The stem supports the plant and transports fluids between the roots and leaves. Leaves are responsible for photosynthesis, where they convert sunlight into energy. Flowers are the reproductive part of the plant, and fruits contain seeds for reproduction.
2. How do plants perform photosynthesis?
Ans. Plants perform photosynthesis by using sunlight, carbon dioxide from the air, and water from the soil. In the leaves, chlorophyll absorbs sunlight, which helps convert carbon dioxide and water into glucose (a type of sugar) and oxygen. This process is essential for providing energy to the plant and releasing oxygen into the atmosphere.
3. Why are plants important to the environment?
Ans. Plants are crucial to the environment as they produce oxygen through photosynthesis, which is necessary for most living organisms. They also help in maintaining the ecosystem by providing food and habitat for various animals. Additionally, plants prevent soil erosion, regulate the water cycle, and help in climate regulation by absorbing carbon dioxide.
4. What are the different types of plants?
Ans. There are several types of plants, including flowering plants (angiosperms), non-flowering plants (gymnosperms), ferns, and mosses. Flowering plants produce flowers and seeds, while non-flowering plants bear seeds in cones. Ferns reproduce through spores and have large leaves called fronds, while mosses are small, non-vascular plants that also reproduce via spores.
5. How do plants adapt to their environment?
Ans. Plants adapt to their environment in various ways. For instance, desert plants have thick, waxy leaves to reduce water loss, while aquatic plants have flexible stems and wide leaves to float on water. Some plants develop deep roots to access water, while others may have shallow roots to absorb rainfall quickly. These adaptations help them survive and thrive in their specific habitats.
