Photosynthesis

• What pigment is primarily responsible for absorbing light energy in photosynthesis?

  Chlorophyll
• What does the equation 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2 represent?

  The conversion of carbon dioxide and water into glucose and oxygen
• What is the process called that converts glucose and oxygen into carbon dioxide and water?

  Cellular respiration
• What does the equation C6H12O6 + 6O2 → 6CO2 + 6H2O represent?

  The process of cellular respiration
• What are the main components involved in photosynthesis?

  • Light energy
  • Chlorophyll (pigment)
  • Water (H2O)
  • Carbon dioxide (CO2)
  • Glucose (C6H12O6)
  • Oxygen (O2)
• What is the number one source of energy for photosynthesis?

  The Sun
• What does the term "photosynthesis" literally mean?

  "Putting together with light"
• What do plants and algae use to make their own energy?

  Energy from sunlight
• What are the reactants in the photosynthesis chemical reaction?

  6H2O and 6CO2
• What is produced as a result of photosynthesis?

  C6H12O6 (glucose) and 6O2 (oxygen)
• What part of the plant does photosynthesis occur in?

  Chloroplasts
• Where does water enter the plant for photosynthesis?

  Roots
• Where does carbon dioxide enter the plant?

  Stomata
• What is the initial source of energy to make glucose in photosynthesis?

  Sunlight
• What are the main components involved in photosynthesis?

  • Reactants: Water (H2O) and Carbon Dioxide (CO2)
  • Products: Glucose (C6H12O6) and Oxygen (O2)
  • Energy source: Sunlight
• What are the functions of stomata in leaves?

  • Small openings on the underside of leaves
  • Allow gas exchange (CO2 in, O2 out)
  • Regulate water loss
• What is the role of chloroplasts in photosynthesis?


  • Contain chlorophyll
  • Site of photosynthesis reactions
  • Convert light energy into chemical energy
• How do the reactants and products of photosynthesis relate to each other?

  • Reactants (H2O and CO2) are transformed into products (C6H12O6 and O2)
  • Energy from sunlight drives the chemical reaction
  • Essential for plant growth and oxygen production
• More Carbon Dioxide means faster/more photosynthesis
• In what part of the plant does photosynthesis occur?

  the leaves
• In what part of the plant does water enter?

  the roots
• Where are chloroplasts located?

  In the leaves
• What is the equation for photosynthesis?


  6H20+6CO2+Sunlight/Energy=C6H12O6+6O2
• What’s the equation for cellular respiration?


  6O2+C6H12O6=Sunlight/Light energy+6H2O+6CO2
• Chloroplasts contain chlorophyll which is a pigment that absorbs light.
• A pigment is a light absorbing molecule.
• Chlorophyll gives plants their green color.
• The two reactions of photosynthesis are light dependent and light independent reactions
• The light independent reactions are also known as the calvin cycle.
• What do light dependent reactions do?

  They take sunlight and turn into chemical energy (ATP).
• What are the reactants and products of light dependent reactions?

  reactants: sunlight, water, ADP, and NADP+

  products: oxygen, ATP, NADPH
• What do light independent reactions do?


  Take carbon dioxide and make glucose
• What are the reactants and products of light independent reactions?

  reactants: Carbon Dioxide, ATP, NADPH

  products: Glucose, ADP, NADP+
