Q

6 steps in photosynthesis in order

A
  1. the plant draw up water through its roots
  2. the leaves take in CO2 from the air
  3. the leaves trap energy from sunlight
  4. The plant uses the energy of sunlight to turn water and co2 into sugars and oxygen
  5. the plant releases oxygen
  6. the plant uses the sugars for growth
