📌 Key Concepts

✦ Biodiversity = variety of plants, animals, microorganisms in a region

✦ Plants: Herbs (soft stem), Shrubs (woody, medium), Trees (tall, hard trunk)

✦ Climbers need support; Creepers spread along the ground

✦ Taproot (one main root, dicots) vs Fibrous root (many thin roots, monocots)

✦ Reticulate venation (net-like, dicots) vs Parallel venation (monocots)

✦ Animals by habitat: Aquatic, Terrestrial, Amphibians

✦ Adaptation = special features helping organisms survive in their environment
