question 3

• photosynthesis


  the process by which plants use sunlight to synthesize nutrients from carbon dioxide and water
• equation reactants


  water and carbon dioxide
• equation used


  chlorophyll and sunlight
• equation products


  glucose and oxygen
• factors affecting photosynthesis


  light intensity:

  • without enough light, plant cannot photosynthesize quickly
  • increasing light intensity increases the rate of photosynthesis
• factors affecting photosynthesis


  CO2 concentration:

  • without CO2 plant cannot photosynthesize properly, even with enough light and temp
• factors affecting photosynthesis


  Temperature:

  • plants cannot photosynthesize if it is too hot or too cold
• compensation point


  when the rate of photosynthesis and respiration are the same
