Answer Key
Section A: MCQ Answers
- (c) Pea
- (b) Fibrous root
- (c) Leaf
- (c) Fish
- (b) Fat storage in humps
- (b) Tulsi
- (b) Reticulate
- (c) Frog
- (b) Absorbing water and minerals
- (b) Chipko Movement
Section B: Short Answers
- Biodiversity refers to the variety of living organisms found in an ecosystem. It is important for maintaining ecological balance, supporting food chains, and promoting sustainability.
- Shrubs are medium-sized plants with multiple woody stems (e.g., Hibiscus), while trees are large, tall plants with a single thick stem (e.g., Mango).
- Taproot System (e.g., Mango) has one main root with smaller branches. Fibrous Root System (e.g., Grass) has many thin roots growing from the base of the plant.
- Mountain goats have sharp, strong hooves for climbing rocky surfaces, thick fur for warmth, and compact bodies to conserve heat.
- Monocots have one cotyledon, parallel venation, and fibrous roots (e.g., Wheat). Dicots have two cotyledons, reticulate venation, and taproots (e.g., Mango).
Section C: Application-Based Answers
- Birds have hollow bones to reduce weight, streamlined bodies for smooth flight, and strong wing muscles for movement.
- Desert plants have thick stems to store water, spines instead of leaves to reduce water loss, and deep roots to absorb water.
- Forests provide oxygen, support biodiversity, prevent soil erosion, and regulate climate.
Section D: Long Answers
- Animals are classified based on habitat into:
- Terrestrial (land animals): Lion, Elephant
- Aquatic (water animals): Fish, Dolphin
- Amphibians (land & water animals): Frog, Tortoise
- Aerial (flying animals): Eagle, Pigeon
- Impact of Deforestation:
- Loss of biodiversity
- Increase in carbon dioxide levels
- Soil erosion and desertification
Ways to Prevent: - Afforestation
- Reducing paper and wood usage
- Enforcing wildlife protection laws
- Diagram of Monocot and Dicot Seeds
- Differences:
- Cotyledons: Monocots have one, dicots have two.
- Venation: Monocots have parallel, dicots have reticulate.
- Root System: Monocots have fibrous, dicots have taproots.
Section E: Practical-Based Answer
- The plant observed has reticulate venation, meaning it is a dicot. Dicot plants usually have a taproot system. This helps them grow deep into the soil and absorb nutrients efficiently.
