Key concepts
Why it matters
This objective helps connect Photosynthetic reaction to exam-style questions, flashcards, and revision notes for Photosynthesis.
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.
