photosynthesis

• What is photosynthesis?


  Photosynthesis is a complex biological process used by plants, algae, and some bacteria to convert light energy into chemical energy.
• Why is photosynthesis fundamental for life on Earth?


  It produces oxygen and organic compounds that form the basis of most food chains.
• What are the key points of photosynthesis?


  • It's a light-dependent process
  • Occurs in chloroplasts in plant cells
  • Involves chlorophyll, a green pigment that absorbs light
• What is the role of chlorophyll in photosynthesis?


  Chlorophyll absorbs light energy necessary for the process of photosynthesis.
• What are the reactants of photosynthesis?


  The reactants are carbon dioxide, water, and light energy.
• What are the products of photosynthesis?


  The products are glucose and oxygen.
• What is the basic equation for photosynthesis?


  6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ + 6O₂
• How do you balance the equation for photosynthesis?


  You ensure that the number of each type of atom is the same on both sides of the equation.
• What are the stages of photosynthesis?


  1. Light-dependent reactions
  2. Light-independent reactions (Calvin cycle)
• Where do light-dependent reactions occur?


  They occur in the thylakoid membranes of the chloroplast.
• What happens during the light-dependent reactions?


  Chlorophyll absorbs light energy, splits water molecules, and produces ATP and NADPH.
