Chlorophyll - GCSE Biology Definition

Chlorophyll is a green pigment found in the chloroplasts of plant cells that is crucial for photosynthesis, the process by which plants make their own food. It absorbs sunlight, specifically blue and red light, and converts it into chemical energy, which helps turn carbon dioxide and water into glucose and oxygen. Chlorophyll is what gives plants their green colour and is vital for their growth and food production. Understanding chlorophyll is important for GCSE Biology students, as it helps explain how plants work and why they are essential for life on Earth.
