Quick student answer

How does photosynthesis work?

Direct answer

In Biology, this page helps you answer questions about photosynthesis within Photosynthesis. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are endothermic reaction and photosynthesis.

Key terms

  • endothermic reaction: A reaction that absorbs energy from the surroundings, such as photosynthesis, where light energy is used to convert carbon dioxide and water into glucose and oxygen.
  • photosynthesis: The process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Common trap

Misunderstanding Endothermic Reactions: Remember that endothermic reactions absorb energy from their surroundings. In photosynthesis, light energy is absorbed to convert carbon dioxide and water into glucose and oxygen.
