    • Anaerobic Respiration

      The process by which cells produce energy without using oxygen, resulting in a small amount of ATP and lactic acid production.
    • Aerobic Respiration

      The process by which cells produce energy using oxygen, resulting in a large amount of ATP production and no lactic acid production.
    • Glucose

      A type of sugar that cells use as a source of energy.
    • What is the process that plants use to trap light energy?
      Photosynthesis
    • What type of reaction is photosynthesis?
      Endothermic reaction
    • From what does a seedling derive its energy to grow?
      Light energy trapped by photosynthesis
    • Where does photosynthesis take place in a plant?
      In the leaves
    • What green chemical do leaves contain that absorbs light energy?
      Chlorophyll
    • What are the inputs for the photosynthesis reaction?
      Carbon dioxide and water
    • What is produced as a byproduct of photosynthesis?
      Oxygen
    • What is the word equation for photosynthesis?
      Carbon dioxide + water → glucose + oxygen
    • What is the chemical formula for carbon dioxide?
      CO<sub>2</sub>
    • What is the chemical formula for water?
      H<sub>2</sub>O
    • What is the chemical formula for glucose?
      C<sub>6</sub>H<sub>12</sub>O<sub>6</sub>
    • What is the chemical formula for oxygen?
      O<sub>2</sub>
    • What happens to the rate of photosynthesis when light intensity is increased?
      The rate of photosynthesis increases
    • What does it mean if light intensity is a limiting factor?
      Photosynthesis is not as fast as possible
    • What happens when light intensity is increased beyond a certain point?
      The rate of photosynthesis levels off
    • What is the next limiting factor after light intensity?
      The level of carbon dioxide
    • What happens to the rate of photosynthesis when carbon dioxide levels are increased?
      The rate of photosynthesis increases
    • What does it indicate when carbon dioxide is a limiting factor?
      Photosynthesis is not as fast as possible
    • What other factors can affect the rate of photosynthesis?
      Amount of chlorophyll and temperature
    • How does the amount of chlorophyll affect photosynthesis?
      Less chlorophyll means lower photosynthesis rate
    • How does temperature affect the enzymes involved in photosynthesis?
      Higher temperatures increase enzyme activity
    • What happens to enzymes if the temperature continues to increase?
      They will denature and activity falls
    • What are the factors that affect the rate of photosynthesis?
      • Light intensity
      • Carbon dioxide levels
      • Amount of chlorophyll
      • Temperature
    • What is the overall process of photosynthesis?
      1. Light energy is absorbed by chlorophyll
      2. Carbon dioxide and water are taken in
      3. Glucose and oxygen are produced
    • How do light intensity and carbon dioxide levels affect photosynthesis?
      • Increased light intensity raises photosynthesis rate
      • Increased carbon dioxide levels also raise photosynthesis rate
      • Both can become limiting factors
    • What happens to the rate of photosynthesis when temperature increases?
      • Rate increases with temperature up to a point
      • Beyond that point, enzymes denature
      • Rate of photosynthesis falls
