Biology Write- up on Petiole Length

Aim: To test whether there was any passing in heights of cl over leaves stiring on the grazed and un-grazed Kristin fields as calculated by petiole aloofness. Hypothesis: The medick encompassing treatments allow for develop two variations and in my opinion the iodin that deforms in the un-grazed argona will be taller as measured by petiole length. This is because the length of the petiole will not devote been altered comp ard to the medic plants in the grazed area. The main emergency for plant growth is photosynthesis so when they clover plants are curb altering their growth the plant in the grazed are will need not as much cheerfulness as the un-grazed for photosynthesis. Wind and interactions among animals will keep this squiffy and so the plant in the grazed should not grow over a certain height because if it was two grow high then its mean height it talent be short-winded over. One much than problem is competition between the un-grazed clover plants as th ey will be fighting for resources and this might quail the amount available for other species and alter plant growth.

The t-test assesses whether the office of the two groups are statistically different from from each hotshot other, this experiment, so competition will be much more higher for the taller plants in ordination to receive maximum sun and nutrition and the tramp be as strong as surrounding plants would be breaking the wind,Data Collection:Length of clover petioles as measured by the average length (mm) of a sample of petioles in grazed and un-grazed grass conditions.
