Photosynthesis is one of the most fundamental biological processes on Earth, and it’s a must-know chapter for every NEET aspirant. Not only does it appear in every NEET exam, but it also forms the conceptual base for many future chapters like Plant Physiology and Ecology. In this article, you’ll learn everything you need — the concepts, mechanisms, diagrams, shortcuts, and previous year NEET questions — all explained in a student-friendly, simple language. 🌿 Understanding photosynthesis: Photosynthesis is the biological process through which green plants, algae, and some bacteria convert light energy into chemical energy, stored in the form of glucose. The general equation is: 6CO_2 + 12H_2O → C_6H_{12}O_6 + 6O_2 + 6H_2O Key Concept: Chlorophyll pigments capture sunlight, water provides electrons, and carbon dioxide is the carbon source fo...
