2. Germination

3.  Water  Warmth  Oxygen

4.  Water- allows the embryo to swell up and start cell division, Softens the seed coat, Enzymes will break the food stored in.  Warmth- Provides necessary heat for the growth  Oxygen- used for respiration to release energy by breaking down food in to glucose  Glucose + Oxygen Carbon dioxide + water

5.  After germination plants makes food by photosynthesis. Can you write down the equation for photosynthesis?
