Study Notes
Glucose Use in Plants
- Glucose, a product of photosynthesis, is used for various plant functions
- Growth and development are supported by glucose
- Glucose is stored for future use
- Respiration uses glucose to release energy
- Fruit and seed production rely on glucose
- General plant maintenance also requires glucose
Translocation
- Translocation is the movement of soluble photosynthesis products (glucose) from leaves to other plant parts
- Food moves from production areas to utilization/storage areas via the phloem
- Specialized phloem cells (sieve tubes) transport organic compounds (glucose, proteins, lipids) within plants
- This transport system is crucial for nutrient distribution throughout the plant
- Translocation uses energy that creates osmotic pressure for upward and downward food movement
Food Storage
- Specific plant parts modify to form food storage organs
- The plant part storing food often becomes large enough to hold the food
- Examples of storage organs include taproots (carrot, beetroot), leaves (spinach, cabbage), stem tubers (Irish potato, sweet potato), root tubers (onion, garlic), fleshy leaves (tomato), fruit (groundnuts, beans), seeds (rice, millet), rhizomes (ginger), and stems (sugar cane)
Respiration
- Respiration is a process where living things break down glucose in the presence of oxygen to release energy
- It's referred to as oxidation because it's an oxygen-dependent process
- Word equation: Oxygen + Carbohydrates → Water + Carbon Dioxide + Energy
- Chemical equation: 6O₂ + C₆H₁₂O₆ → 6H₂O + 6CO₂ + Energy
- Respiration takes place inside plant cells' mitochondria
- Oxygen enters the plant through diffusion, possibly from leftover photosynthesis or through water
