Xylem and phloem

• Phloem is made up of?

  Living cells
• Xylem is made up of?

  Dead cells
• Root hair cell:


  Absorbs water by osmosis and mineral ions by diffusion and active transport
• Does root hair cell have a large of small surface area?


  Large surface area
• Phloem:


  Transports water and minerals from the roots to the leave in an upward flow
• Transpiration:


  Takes place via xylem vessels.
• Translocation:


  The movement of sugars (sucrose) and amino acids
• Equation for photosynthesis:


  Carbon dioxide + Water ----> Glucose + Oxygen

  Energy
• The energy needed for photosynthesis comes from

  Light
• Energy is absorbed by a green pigment called

  Chlorophyll
• If the temprature is decreased the rate of photosynthesis will 


  Decrease
