Photosynthesis and Plants

• Photosynthesis Equation

  6Co2 + 6H2O - C6 H12 O6 + 6o2
• Photosynthesis Word Equation

  Carbon Dixoide + Water - Glucose + Oxygen
• Why is a leaf DeStarched

  Remove all starch present in the plant before the experiement is carried out
• How to DeStarch a leaf

  leave in a dark cupbaord for 48 hours
• Photosynthesis


  Process where plants make their own food using light energy
• Limiting factors for Repiration

  Temperature

  Co2 Concentration

  Light Intensity
• What is the limiting factor

  A)

  
• Photosynthesis happens during the day
• Respiration happens at all times
• Stucuture of a leaf

  A) upper epidermis

  B) wxy cuticle

  C) palisade mesophyll

  D) spongy mesophyll

  E) stomata

  F) gaurd cell

  
• Palisade Mesophyll - where photosynthesis occurs
• Gaurd Cells - controls opening/closing of stomata
• Spongy Mesophyll - gas exchange, water vapour loss
• Waxy Cuticle - prevents water loss from plant
• High Co2 Concentration

  hydrocarbonate indicator goes yellow
• Low Co2 Concentration

  hydrocarbonate indicator goes purple
• respiration equation

  C6H12O6 + 6O2 → 6CO2 + 6H2O
• respiration equation

  glucose + oxygen -> carbon dioxide + water
