Life Processes

Welcome to one of the heaviest-tested chapters of Class 10 Science — typically 8-12 marks every Board exam and 2-3 NEET-foundation questions. We follow the complete journey of a living body: how energy enters via nutrition (autotrophic photosynthesis in plants; heterotrophic feeding in animals), how it is broken down via respiration (aerobic vs anaerobic), how nutrients and oxygen are circulated via the heart-pump and double circulation (in humans) and the xylem-phloem system (in plants), and finally how wastes are filtered out via the kidney's nephron and the plant's specialised excretory pathways. We close with a comparison of unicellular organisms (Amoeba uses simple diffusion) and multicellular organisms (we use specialised organ systems). By the end you'll have mastered every NCERT diagram, every NCERT-canonical phrase, and every Board exam trap — from the C4 leaf cross-section to the four-chambered heart to Bowman's capsule.
