Summary

• Photosynthesis takes place in chloroplast which have chemicals that give organelles green color.
• Chloroplasts has an inner, outer membrane, granum, stroma, thylakoid space, and thylakoid.
• Inside the inner membrane contains thick fluid. This fluid is called stroma.
• Photosynthesis's equation is 6 CO2 + 6H2O -> C6H1206 + 6 O2
• Photosynthesis is divided into two stages. One being light reaction and two being the calvin cycle. Light reaction changes sunlight into chemical energy. Calvin cycle uses carbon dioxide and hydrogen ions to make sugar.
  Concept Check 8.1

1. Draw and label a simple diagram of a chloroplast that includes the following structure: outer and inner membrane, stroma thylakoids



2.What are the reactants for photosynthesis? What are the products?
Reactants are carbon dioxide and water and the products are glucose and oxygen.


3.Name the two main stages of photosynthesis. How are the two stages related?
Light reactions and Calvin cycle are the two main stages of photosynthesis. They are related because they are both used in the photosynthesis and they both change different chemical reactions into different compound.
