4.1.3 Uses of Glucose in Plants

• Plants store glucose as starch
• Steps of photosynthesis in plants

  1️⃣ Light energy is absorbed by chlorophyll

  2️⃣ Water molecules are split into hydrogen and oxygen

  3️⃣ Hydrogen combines with carbon dioxide to form glucose

  4️⃣ Glucose is used for energy or stored as starch
• Glucose is a monosaccharide that serves as an energy source for cellular respiration.respiration
• Match the type of respiration with its key feature:

  Aerobic Respiration ↔️ Requires oxygen

  Anaerobic Respiration ↔️ Does not require oxygen
• Glucose is used to form cellulose for building plant walls
• What form of energy is absorbed by chlorophyll during photosynthesis?

  Light energy
• What is the process by which plants break down glucose to produce energy called?

  Respiration
• Where does aerobic respiration occur in plant cells?

  Mitochondria
• The equation for aerobic respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
• What are the end products of anaerobic respiration?

  Ethanol and carbon dioxide
• What molecule does glucose form to provide structural support in plant cell walls?

  Cellulose
• Starch is used by plants to store excess energy.


  True
• One benefit of storing glucose as starch is that it provides a long-term storage of energy
• Match the benefit of starch storage with its description:

  Energy Reserve ↔️ Starch is broken down to release glucose

  Long-term Storage ↔️ Starch can be stored for long periods

  Structural Support ↔️ Starch contributes to plant integrity
• What role does glucose play as a carbon source in protein synthesis?

  Forms amino acids
• What is glucose stored as in plants for later use?

  Starch
