I want to create a presentation for my MSc defense. I will attach my MSc thesis and the presentation should be based on my thesis. I want 20-25 slides. I want the presentation to include background on diatoms, frustule components and general morphology. In the introduction section I would laso like to show model valve morphologies (from my thesis introduction) that will lead to an introductionary slide about my subject of research, Chaetoceros rostratus. The latter segments should include methods, results and conclusions.
