2. water potential comparison in sweet vs white potato tubers–plasmolysis method, sucrose solution gradients, mass/density change analysis
3. experimental variables in osmosis–abiotic (temperature, light), biotic (tissue maturity), impact and control strategies
4. factors influencing potato cell water potential–solute concentration, vacuole size, dehydration, metabolic activity
5. insecticide effect on thistle leaf length–null hypothesis formulation, t-test analysis, mean and SD comparison, percentage difference
6. photosynthesis in Cabomba under light intensity–hypothesis testing, safety measures, preliminary trials, controlled variables, data recording, limitations of setup
