The student clearly states the independent variable as the concentration of surfactants and the dependent variable as the plasma membrane permeability of Beta vulgaris, indicating a strong grasp of the research question. The method of analysis is well described, detailing how plasma membrane permeability will be assessed through colorimetric measurement of betacyanin leached into the solution. The background theory is effectively presented, connecting key concepts relevant to the research question, and controlled variables are identified with explanations on how they are managed. However, the student does not provide a clear explanation of the choice of techniques for measurement or the sampling technique used, and there is insufficient discussion on the number of trials conducted. Overall, while the methodology is detailed and reproducible, these gaps in explanation could strengthen the research design.
