11.1 Overview on photosynthesis

• What is the word equation for photosynthesis?

  Carbon dioxide + water (+ sunlight)-> glucose + oxygen
• What is the symbol equation for photosynthesis?

  6CO2 + 6H2O -> C6H12O6 + 6O2
• What process do plants use to make their own food?

  Photosynthesis
• Why are plants referred to as autotrophs?

  Because they make their own food through photosynthesis
• What happens to the energy in the food made by plants?

  It is released in cells by respiration
• How do the processes of photosynthesis and respiration relate to each other in plants?

  Photosynthesis produces food, which is then used in respiration to release energy
• Chloroplasts are the cellular organelles within the leaf where photosynthesis takes place.
• Starch grains in the stroma are where carbohydrates produced during photosynthesis are stored.
• The space within chloroplasts is called the stroma.
• thylakoid membranes are also know as...

  lamellae
• lamellae (thylakoid membranes) contain photosynthetic pigments
• Examples of photosynthetic pigments include:

  Chlorophyll a

  Chlorophyll b

  Carotene
• Within the thylakoid membranes, photosynthetic pigments are attached to proteins. what are they called together?

  photosystem
• what is a photosystem?

  photosynthetic pigments attached to proteins.
• what is a photosystem?

  Protein and photosynthetic pigment attached together in the thylakoid membrane. Together they absorb light energy.
