FOCUS QUESTION

How does photosynthesis convert light into stored energy?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Sunlight provides Light Energy.
  • Sunlight absorbed by Chlorophyll.
  • Chlorophyll found in Chloroplasts.
  • Light Energy drives Light Reactions.
  • Chloroplasts site of Light Reactions.
  • Carbon Dioxide (CO₂) enters Calvin Cycle.
  • Water (H₂O) split by Light Reactions.
  • Light Reactions produces ATP & NADPH.
  • Light Reactions releases Oxygen (O₂).
  • ATP & NADPH powers Calvin Cycle.
  • Calvin Cycle produces Glucose (C₆H₁₂O₆).

How to read this map

Begin with the inputs — sunlight, water and carbon dioxide — and follow each labeled line inward to the reactions. Read every connection as a complete statement (concept + linking words + concept), then compare the inputs with the products, glucose and oxygen.

Learning objectives

  • Identify the raw materials and products of photosynthesis.
  • Explain the role of sunlight, chlorophyll and chloroplasts.
  • Distinguish matter inputs from the energy input.
  • Use linking words to describe scientific relationships.
Review standard: The concept set was checked against standard secondary-school biology descriptions. The review date and source notes are maintained whenever the template changes. Sources: OpenStax Biology 2e — Chapter 8: Photosynthesis; CK-12 Biology — Photosynthesis.
