What this chapter is about
On a nature walk with Dr Raghu (a scientist) and Maniram chacha (a community elder who mimics bird calls), students discover the huge variety of plants and animals around them — biodiversity. The chapter then shows how to group living things: plants as herbs, shrubs and trees (plus climbers and creepers); leaves by venation; roots as taproot or fibrous; seeds as dicot or monocot — and how these three features go together. Animals are grouped by movement. Finally it explains why living things differ from region to region — adaptations and habitats (camels, deodar, cactus, rhododendron) — and why we must protect biodiversity.
The six things most worth remembering
1 · Biodiversity
The variety of plants and animals found in a particular region. Each member has a role — plants and animals depend on each other.
2 · Herbs, shrubs, trees
Herb: small, soft green stem (tomato). Shrub: many woody stems branching near the ground (rose). Tree: tall, thick woody trunk, branches high up (mango).
3 · The dicot–monocot chain
Dicot (2 cotyledons) → reticulate venation → taproot (chickpea). Monocot (1 cotyledon) → parallel venation → fibrous roots (maize, wheat).
4 · Adaptations
Special features that let a living thing survive in a region — the cactus's fleshy stem, the deodar's conical shape, the camel's hump and hooves.
5 · Habitat
The place where a plant or animal lives — terrestrial (land) or aquatic (water). Frogs live in both: amphibians.
6 · Protect biodiversity
Habitat damage causes biodiversity loss. Project Tiger (1973), Cheetah Reintroduction (2022), sacred groves and Silent Valley show how to protect it.
