Intr - Lab Report Example In plants, an isolated seedling in fertile soil may have a very high chance of surviving to reproductive maturity. it will probably exhibit an extensive amount of module growth and will eventually produce a large number of seeds (Pujol 2006). However, a seedling that is closely surrounded by neighbours ,shading it with their leaves and depleting the water and nutrients of its soil with their roots, will be very unlikely to survive, and if it does, it will almost certainly form few modules and set few seeds (Wang 2005). Thus, it’s evident that the ultimate effect of competition on an individual is a decreased contribution to the next generation compared with what would have happened had there been no competitors. Thus the main aim of this report will be to test the null hypothesis that there is no statistically significant evidence in the data to show that the data provided is normally distributed. Group plants were collected and put into six pots per group while being planted at densities of 1,2,4,8,16,32 plants for every pot. Then a tray was used for storing tap water. The roots were keenly and carefully washed out in water while ensuring that the whole plant is kept intact. For each pot, the total root weight was taken, total shoot weight as well as total hypocotyls weight and the data recorded in an Excel table. The next step entailed calculating the mean weight (of shoots or roots or hypocotyls) per plant. Calculation of mean weight per plant was done by dividing the weights by the number of plants under study (Bossdorf 2005). Finally, all the contents of each pot were put into one bag and send to the oven – labelling the bag with the group name and plant density. There were a total of 6 bags. All the six bags were put inside another bag to keep them together. One group measured the dried plant parts and the data recorded to be used for analysis. Then graphs of the data were drawn to facilitate evaluation of the relationship between
