9. Factors for Seed Germination 1. Oxygen Living things need oxygen to survive. A seed needs oxygen to germinate. Oxygen in found in spaces in the soil. *Note that seeds should not be buried too deeply within the soil for oxygen to be available. • Oxygen

10. Factors for Seed Germination • 2. Water • Food stored in the seed leaves help the seed to grow. • As the seed grows, water is needed to break the seed coat. • The root helps to anchor the seed and absorb minerals and water from the soil. • Give the optimum amount of water. • (Too much water can cause the root to rot and too little water limits the seed’s growth.)

11. Factors for Seed Germination • 3. Warmth Seeds generally germinate within a t_ _ _ _ _ _ _ure range. *Note that many seeds germinate at t_ _ _ _ _ _ _ures between 16 and 24 degree celsius.
