Introduction
This document contains carefully selected exam-style questions and clear answers on
photosynthesis. It is designed to help high school students quickly understand key concepts, revise
efficiently, and prepare confidently for biology tests and examinations. The questions focus on
common exam areas, definitions, explanations, and frequently tested ideas.
Brief Overview: Photosynthesis
Photosynthesis is the process by which green plants manufacture their own food using carbon
dioxide, water, and sunlight. The process takes place mainly in the leaves, where chlorophyll absorbs
light energy. This energy is used to produce glucose, which serves as food for the plant, while oxygen
is released as a by-product. Photosynthesis is essential because it forms the basis of food chains and
supplies oxygen needed for respiration.
