Abstract
An abstract is an abbreviated summary of a research article, review, or any in-depth analysis of a particular subject or discipline, and is often used to help the reader quickly ascertain the paper s purpose. When used, an abstract always appears at the beginning of a manuscript, acting as the point-of-entry for any given scientific paper or patent application.
Introduction
The subject of my Extended Essay is the "Effects of light intensities on plant photosynthesis measured by the volume of oxygen produced". It is contained within the IB syllabus in Topic 7 on Cells Respiration and Photosynthesis. I intend to observe the volume of oxygen emitted by Elodea pond weed proportional to the differences in light intensities. After
