FAQs on Adaptations in Plants - 2 Class 6 Worksheet Science

1. What are some common adaptations in plants to survive in different environments?
Ans. Some common adaptations in plants to survive in different environments include thorns for protection, deep root systems for accessing water, and waxy coatings on leaves to reduce water loss.
2. How do plants adapt to low light conditions?
Ans. Plants adapt to low light conditions by growing larger leaves to capture more light, or by developing specialized pigments that can absorb light more efficiently.
3. What are some examples of plants that have adapted to extreme temperatures?
Ans. Some examples of plants that have adapted to extreme temperatures include cacti, which have thick stems to store water in hot deserts, and mosses, which can survive in cold Arctic regions.
4. How do plants adapt to limited water availability?
Ans. Plants adapt to limited water availability by having small leaves to reduce water loss through transpiration, or by developing extensive root systems to absorb water from deep in the soil.
5. How do plants adapt to nutrient-poor soil?
Ans. Plants adapt to nutrient-poor soil by forming symbiotic relationships with fungi to help with nutrient absorption, or by developing mechanisms to trap and digest insects for additional nutrients.
