NEET Biology-02 How Plants and Animals Are Built

You encounter plant and animal structures every day—often without noticing the rules that make them easy to identify. If exams like NEET keep tripping you up on “root vs stem,” inflorescence order, or tricky biology look-alikes, this guide helps you connect the clues and answer with confidence. Start with plant morphology: how the radicle becomes a tap root in dicots (mustard, gram), why monocots (wheat) shift to fibrous roots, and how to spot adventitious roots in grass, banyan, and Monstera. You’ll match classic root modifications to function—storage forms like fusiform radish, conical carrot, and tuberous sweet potato (and the trap: sweet potato is a root, potato is a stem). Then learn the stem’s signature (nodes, internodes, buds) and classify underground, subaerial, and aerial stem modifications—from ginger rhizomes to grape tendrils and Bougainvillea thorns. Leaf basics follow: venation, phyllotaxy, simple vs compound leaves (with the “bud test”), plus modifications like pea tendrils and pitcher-plant traps. You’ll also master inflorescence types, floral whorls, ovary position, aestivation, placentation, fruit types, seed structure, and germination patterns—then tie it all together with floral formulae and key families (Malvaceae, Cruciferae, Leguminosae, Compositae, Graminae). Finally, revise plant tissues and core animal topics: epithelial/connective/muscle/neural tissues and a focused, exam-ready frog unit from morphology to metamorphosis.
