1. Time-course enzymatic reaction using invertase to hydrolyze sucrose and detection via Benedict’s test.
2. Determining optimum Benedict’s test temperature and solution volumes for accurate reaction monitoring.
3. Potato tissue mass changes in different sucrose concentrations to investigate osmotic effects.
4. Analyzing water movement across potato cells by correlating sucrose concentration with water potential gradients.
5. Plan diagram of plant leaf cross-section, highlighting adaptations for dry habitats such as thick cuticles or reduced stomatal density.
6. Comparative analysis of leaf structures between specimens from different geographic regions to assess xerophytic features.
