Example: In a park, we might see different types of trees, flowers, birds, insects, and small animals. Grouping Plants- Based on similarities and differences among them. A. Based on Size and Stem: 1. Trees: Tall, hard thick stems, branches high up Example: Mango tree, Neem Tree, Banyan Tree 2. Shrubs: Medium height, hard thin stems, branches near ground Example: Rose plant, Hibiscus plant 3. Herbs: Short, soft green stems Example: Tomato plant, Basil, Mint 4. Climbers: Weak stem need support to climb and grow Example: Money Plant, Bean Plant 5. Creepers: Creep along the ground Example: Pumpkin Plant, Sweet Potato B. Based on Leaf Venation: The pattern of veins (thin lines on the leaves) of the leaf 1. Reticulate Venation: Net-like pattern of veins on both sides of a thick middle vein. Example: Hibiscus leaf Hibiscus leaf with reticulate venation

Taproot System: One main root with smaller side roots arising from it. Example: Mustard plant, Hibiscus plant 2. Fibrous Root System: Bunch of similar-sized thin roots arising from the base of the stem. Example: Grass, Onion Note: Relationship Between Leaf Venation and Types of Roots 1. Parallel Venation and Fibrous Roots: Plants with parallel venation in their leaves typically have fibrous roots. Example: Grass. The leaves have veins that run parallel to each other, and the root system is made up of many thin, fibrous roots that spread out in the soil. 2. Reticulate Venation and Taproots: Plants with reticulate venation in their leaves usually have a taproot system. Example: Rose. The leaves have a network of veins forming a web-like pattern, and the root system consists of one main root (taproot) that goes deep into the soil, with smaller lateral roots branching off from it. Cotyledon: A cotyledon is the first leaf or one of the first pair of leaves that develop from a seed. It provides nutrients to the young plant.

Monocotyledons (Monocots): Seeds have single thin cotyledon Example: Maize, Wheat, Rice Important Note: ❖ Dicots usually have reticulate venation and taproots ❖ Monocots usually have parallel venation and fibrous roots Grouping Animals: Based on different types of movement A. Based on Movement: 1. Flying: Birds, insects (use wings) 2. Walking/Running: Dogs, cats, cows (use legs) 3. Swimming: Fish (use fins) 4. Crawling: Snakes, worms B. Based on Habitat: 1. Terrestrial: Live on land Examples: Cows, ants, trees 2. Aquatic: Live in water Examples: Fish, water plants 3. Amphibians: Live both on land and in water Example: Frog

Cactus: Thick, fleshy stems to store water (desert adaptation) 2. Deodar tree: Conical shape, sloping branches to let snow slide off (mountain adaptation) 3. Camel: a. In hot desert: Long legs, wide hooves (for walking on sand) b. In cold desert: Shorter legs (for mountainous regions), two humps (for food storage) Habitats A habitat is the natural home of a plant or animal. Examples: 1. Sea turtle's habitat: Ocean 2. Camel's habitat: Desert 3. Rhododendron's habitat: Mountains Importance of Protecting Biodiversity ❖ Habitats can be damaged by human activities ❖ This leads to loss of homes and food for animals and plants ❖ We must protect biodiversity to keep our planet full of life Example: Project Tiger to protect Bengal Tigers in India
