For this investigation I have decided to find out how temperature and oxygen affect the rate of germination, providing there are no other variables i.e. reasonable amount of water and light. For the first part of my experiment I will concentrate on varying the oxygen I predict that the less oxygen in the flask the fewer seeds that will germinate. Without oxygen, respiration cannot take place and as a result the seed cannot get the energy to make new cells. In our atmosphere there is about 20% of oxygen in the air, since the seeds are receive adequate amount of oxygen for respiration.
