  • Transport in plants
    • Xylem
      • Xylem transports water and mineral salts from the roots up to other parts of the plant.
      • contain no cytoplasm
      • impermeable to water
      • tough walls
    • Phloem
      • Phloem transports sucrose and amino acids  between the leaves and other parts of the plant.
      • contain cytoplasm
      • translocation is where it transports sucrose and amino acids up and down the plant
    • transpiration stream
      • transporting mineral ions
      • providing water to keep cells turgid
      • providing water to leaf cells
      • keeping the leaves cool
      • factors affecting rate of transpiration
        • temperature
        • humidity
        • wind speed
        • light intensity
