Photosynthesis and limiting factors

Cards (11)

  • Photosynthesis
    Process that produces glucose using light
  • Photosynthesis
    1. Carbon dioxide + water
    2. Light
    3. Glucose + oxygen
  • Ways plants use glucose

    • Respiration - provides energy
    • Making cellulose - for strong plant cells
    • Making amino acids - combined with nitrates for proteins
    • Stored as fats and oils
    • Stored as starch
  • Starch
    • Insoluble, better for storing than glucose
  • Limiting factors

    Factors that affect the rate of photosynthesis
  • Limiting factors of photosynthesis

    • Light intensity
    • Carbon dioxide concentration
    • Temperature
  • Any of the three limiting factors can become the factor limiting photosynthesis from happening any faster</b>
  • The limiting factor depends on the environmental conditions
  • If it's warm enough and bright enough, the amount of carbon dioxide is usually limiting
  • Chlorophyll
    Can also be a limiting factor of photosynthesis
  • Factors like disease or environmental stress can reduce the amount of chlorophyll, limiting the rate of photosynthesis
