Introduction

Investigating the Conditions Needed for Germination 1. INTRODUCTION All seeds are in the period of dormancy before emerging to growth. Dormancy ends when germination takes place. Germination is the growth of a germinal plant included within a seed. Different variables are needed for successful germination to occur. Only under favorable conditions does a seed begin to germinate resuming the embryonic tissues growth. 1.2 Research Question The purpose of this experiment is to conduct a coherent experiment in order to find out what are the requirements for germination to take place. What conditions the seed has to have to begin the germinating process. 1.3 Hypothesis Using previous knowledge I can predict that the seeds will require water, oxygen, light and nutrients from soil in order for germination to take place. 1.4 Variables The independent variables are going to be sun light, water, oxygen, temperature and pH levels. ...read more.

Graph 2. 3.1 Description The first table shows us generally in which conditions germination occurred. Which shows us that in light the seeds germinate definitely. From the graphs we can see that water has a clear dependency on the growth of the seeds. The more water the seeds got the more visible growth they seemed to produce. 4. CONCLUSION 4.1 Support of Hypothesis The data confirms the hypothesis up to a certain degree. From the results it is visible that light plays a crucial role in the germinating process. The seeds germinated in day light and did not germinate in the darkness. Also of course water was a crucial component in germination. There did occur some conflicts with the prediction of oxygen. However the seeds did not need any type of nutrients from soil since only tissue paper was being used. ...read more.

Conclusion

The biggest growth occurred in the Petri dish without oxygen. However based on previous knowledge this seems contradictory. Germination process cannot occur without oxygen. The lids that were on top of the Petri dish did not conceal all the air from coming into the dish. The dish worked as a greenhouse for the seeds. Providing warmth and moisture and ideal conditions for germination. Whenever the seeds were watered oxygen got into the Petri dish. The seeds should have had another layer of tissue paper on top in each condition to trap the moisture. Since under the artificial light the water condensed easily and only dried the seeds therefore the germination process could not begin. 5.2 Solutions All of the petri dishes should have been covered with a lid to keep the moisture since the seeds were not watered regularly. Some kind of apparatus should have been developed in order to keep the air out. So that the seeds would be in a compact environment without oxygen. ...read more.
