2. Design of experiments for enzyme kinetics, including preparation of beads, timing of reactions, and error identification with proposed improvements.
3. Graphical representation and analysis of oxygen evolution during catalase-mediated hydrogen peroxide breakdown.
4. Large plan and detailed cellular drawings of plant organ cross-sections, emphasizing vascular bundle structures and epidermal cell sizes.
5. Calculation of actual dimensions from photomicrographs using given magnifications and measurement scales.
6. Comparative analysis of vascular structures between different plant species, highlighting observable differences in anatomy and cell organization.
