Photosynthesis is the process by which plants convert light energy into chemical energy (glucose). It occurs in two main stages: **Light Reactions (in thylakoids)**: - Input: Light, water (H₂O), ADP, NADP⁺ - Process: Chlorophyll absorbs light, water is split - Output: Oxygen (O₂), ATP, NADPH **Dark Reactions/Calvin Cycle (in stroma)**: - Input: CO₂, ATP, NADPH from light reactions - Process: Carbon fixation and reduction - Output: Glucose (C₆H₁₂O₆) Overall equation: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂ + 6H₂O

The chain rule is used to find the derivative of composite functions. If you have f(g(x)), the derivative is f'(g(x)) × g'(x). Here's a step-by-step example with h(x) = (3x² + 1)⁵: 1) Identify outer function: f(u) = u⁵ where u = 3x² + 1 2) Find f'(u) = 5u⁴ 3) Identify inner function: g(x) = 3x² + 1 4) Find g'(x) = 6x 5) Apply chain rule: h'(x) = f'(g(x)) × g'(x) = 5(3x² + 1)⁴ × 6x = 30x(3x² + 1)⁴
