1. Measuring plant tissue flexibility using sodium chloride solutions to estimate water potential effects on cells.
2. Standardization of experimental variables, accuracy improvements in measuring the angle of bend in plant tissues.
3. Data plotting to determine the relationship between sodium chloride concentration and tissue bending, with graphical interpolation for unknown concentrations.
4. Water potential effects on plant cells placed in varying solutions, including osmotic behavior and turgidity changes.
5. Microscopic examination of plant leaf structures to assess tissue organization and xerophytic adaptations.
6. Calculation of leaf thicknesses and analysis of adaptations for dry conditions in different plant species..
