Class 6 Science curiosity Chapter 2 Diversity in the Living World
Q: What is biodiversity?
A: Biodiversity refers to the variety of plants and animals found in a particular region.
Q: How can plants be grouped based on their height and stem type?
A: Plants can be grouped into herbs, shrubs, and trees based on their height and stem characteristics.
Q: What are the two main types of leaf venation?
A: The two main types of leaf venation are reticulate venation and parallel venation.
Q: What is the difference between taproot and fibrous root systems?
A: Taproots have one main root with smaller side roots, while fibrous roots have many thin roots of similar size.
Q: How are dicot and monocot plants different?
A: Dicot plants have seeds with two cotyledons, reticulate leaf venation, and taproots. Monocot plants have seeds with one cotyledon, parallel leaf venation, and fibrous roots.
Q: What is an adaptation?
A: An adaptation refers to special features that enable plants and animals to survive in a particular environment or habitat.
Q: What is a habitat?
A: A habitat is the natural environment where a plant or animal lives and grows.
Q: How can animals be grouped based on their habitat?
A: Animals can be grouped into terrestrial (land-dwelling) and aquatic (water-dwelling) based on their habitat.
Q: Why is it important to protect biodiversity?
A: Protecting biodiversity is important to ensure the planet remains full of life and to help plants and animals survive and thrive.
Q: What is venation in leaves?
A: Venation refers to the pattern of veins on a leaf.
Q: What are sacred groves?
A: Sacred groves are undisturbed patches of forests protected by local communities, serving as treasures of biodiversity.
Q: Who is known as the “Birdman of India”?
A: Salim Ali is known as the “Birdman of India” for his extensive work on Indian birds.
Q: What is the purpose of grouping plants and animals?
A: Grouping makes it easier to understand and study plants and animals based on their similarities and differences.
Q: What are amphibians?
A: Amphibians are animals that can live both in water and on land, like frogs.
Q: How do camels adapt to desert conditions?
A: Camels have adaptations like storing food in humps, excreting small amounts of urine, and not sweating to conserve water.
Q: What is the difference between hot desert camels and cold desert camels?
A: Hot desert camels have longer legs and one hump, while cold desert camels have shorter legs, two humps, and long hair to survive cold winters.
Q: What government project was initiated in 1973 to protect tigers?
A: Project Tiger was initiated in 1973 to protect the declining population of Bengal Tigers.
Q: How does damage to habitats affect biodiversity?
A: Damage to habitats results in loss of homes, food, and resources for plants and animals, leading to a loss of biodiversity.
Q: Who was Janaki Ammal and what was her contribution?
A: Janaki Ammal was an Indian botanist who helped document and preserve India’s plant biodiversity and played a key role in the ‘Save Silent Valley’ movement.
Q: What is the Save Silent Valley Movement?
A: It was a successful 10-year environmental movement in Kerala to prevent the construction of a hydroelectric dam that would have destroyed a rich, biodiverse forest.
Q: How do deodar trees adapt to snowy mountain conditions?
A: Deodar trees have a conical shape and sloping branches that allow snow to slide off easily.
Q: What are the differences in rhododendrons found in different regions?
A: Rhododendrons in the Nilgiris are shorter with smaller leaves to withstand heavy winds, while those in Sikkim are taller.
Q: What is the Cheetah Reintroduction Project?
A: It’s a project initiated in 2022 to restore the cheetah population in India.
Q: How do fish adapt to living in water?
A: Fish have streamlined bodies and fins that help them swim efficiently in water.
Q: What are some examples of terrestrial habitats?
A: Forests, deserts, grasslands, and mountains are examples of terrestrial habitats.
Q: What are some examples of aquatic habitats?
A: Ponds, lakes, rivers, and oceans are examples of aquatic habitats.
Q: How can students contribute to documenting biodiversity?
A: Students can create a class biodiversity register by consolidating observations from nature walks or field visits.
