FAQs on Class 4 Science - Adaptations in Plants - CBSE Worksheets - 1

1. What are some examples of adaptations in plants?
Ans. Some examples of adaptations in plants include the presence of thorns or spines to deter herbivores, the ability to store water in succulent leaves or stems, and the development of deep root systems to access water in dry environments.
2. How do plants adapt to survive in different climates?
Ans. Plants adapt to survive in different climates by developing various traits. In hot and dry climates, they may have small leaves or thick waxy coatings to reduce water loss. In cold climates, they may have hairy or fuzzy surfaces to trap heat and protect themselves from frost.
3. How do plants adapt to low light conditions?
Ans. Plants adapt to low light conditions by developing larger leaves to capture as much sunlight as possible. They may also have elongated stems to reach higher up towards the light source, or they may have specialized pigments that allow them to absorb light more efficiently.
4. What is the role of adaptation in plant evolution?
Ans. Adaptation plays a crucial role in plant evolution as it allows plants to survive and reproduce in their specific environments. Over time, those plants with beneficial adaptations are more likely to pass on their genes to the next generation, leading to the evolution of new plant species or variations within a species.
5. How do plants adapt to living in aquatic environments?
Ans. Plants that live in aquatic environments have adaptations to help them survive. They may have air-filled structures to provide buoyancy and allow them to float, or they may have specialized tissues that can extract oxygen from the water. Some aquatic plants also have flexible stems that can bend and sway with the water currents.
