INTRODUCTION
It is predicted that different environmental conditions affect the structure of plants. Therefor the amount of sunlight that a plant is exposed too should have an effect on the plant’s structure. For example, it is said that a plant exposed to low sunlight conditions should have larger leaves then a plant exposed to high sunlight conditions. The reason behind this is that a plant with larger leaves has more surface area, therefor it would be able to make more carbohydrates from the sunlight it gathers. And thus produce more flowers and seeds than a plant with smaller leaves in the same environment. And by pruducing more flowers and seeds, it would increase it’s…show more content…
I collected 2 olive leaves from the north side which are exposed to low sunlight density and 2 olive leaves from the south side which are exposed to high sunlight density. I placed the north side leaves in a Ziploc bag labeled north and the south side leaves on another Ziploc bag labeled south in order to avoid getting them confused. I then traced each leaf from the low sunlight environment onto a paper, cut around the outline, weighed the leaves and made sure to keep track of their weight. I also repeated these steps with the leaves from the high sunlight environment. In order to calculate the leaves’ surface area, I used the conversion factor of a 100mm x 100mm paper which is (Mass/Surface Area = .000122mm^2). By knowing the conversion factor of paper, I used (Mass of Common Olive leaf/Conversion Factor = Common Olive Leaf Surface Area) to calculate the surface area of the leaves from different sunlight…show more content…
And the average surface area for the leaves at a high sunlight environment is 453.08mm^2.

Common Olive Surface Area from Low Sunlight Density in (mm^2) 250 | 410 | 417 | 492 | 492 | 492 | 538 | 538 | 538 | 656 | 737 | 738 |

Common Olive Surface Area from High Sunlight Density in (mm^2) 327 | 328 | 328 | 333 | 410 | 445 | 470 | 500 | 574 | 574 | 574 | 574 | The Table of Class Raw Data shows that the leaves at a low sunlight environment have surface areas ranging from 250mm^2-738mm^2. There is one leaf with 250mm^2, one leaf with 410mm^2, one leaf with 417mm^2, three leaves with 492mm^2, three leaves with 538mm^2, one leaf with 656mm^2, one leaf with 737mm^2, and one leaf with 738mm^2. The leaves at a high sunlight environment have surface areas ranging from 327mm^2-574mm^2. There is one leaf with 327mm^2, two leaves with 328mm^2, one leaf with 333mm^2, one leaf with 410mm^2, one leaf with 445mm^2, one leaf with 470mm^2, one leaf with 500mm^2, and four leaves with
