​ Understanding the fundamental characteristics that define life: Growth, Metabolism, and Consciousness.    (NEET – The Living World ): 🌱 What is Living? – Simple Notes 🔹 1.

Metabolism All chemical reactions inside the body = Metabolism Includes: Anabolism (building) Catabolism (breaking) ✔️ This is a defining feature of life ✔️ Happens only in living cells 🔹 4. Cellular Organiz...
