plant structures

• Xylem

  Tubes that carry water and dissolved mineral ions upwards (transpiration)
• Phloem

  Carries sugars (e.g. sucrose) in both directions, translocation
• Roots

  Water enters through osmosis, mineral ions by active transport
• Word equation for photosynthesis

  Water + carbon dioxide ------> glucose + oxygen
• Glucose is used for...

  • respiration
  • making starch/ fat to store energy
  • making cellulose
  • making amino acids for proteins
• Leaf

  Photosynthesis, gas exchange takes place and water evaporates out
