Plant germination

• Plant reproduction

  1. Gamete formation

  2. Making the pollen

  3. Making the eggs

  4. Pollination

  5. Fertilization

  6. Seed and fruit formation

  7. Seed dispersal

  8. Germination
• Conditions needed for germination

  • Water
  • Temperature
  • Oxygen
• Cotyledons


  The food stores which provide the food to get the first bits of growth going until photosynthesis can occur
• Investigating factors needed for germination

  1. Set up 4 tubes with cotton wool and cress seeds

  2. Control variables

  3. Leave for 5 days

  4. Observe results
• • Seed coat can't be broken down without water
  • Boiling stops oxygen getting in, so no respiration
  • Too cold, enzymes can't work
• Covering a tube in foil to block light

  Germination will still occur, but the plant may die later without photosynthesis
