1. Investigating sucrose solution movement using syringe setups and observing transport in vascular tissues.
2. Testing non-reducing sugars in solutions collected over time to determine rates of sucrose diffusion into water.
3. Analyzing semi-quantitative Benedict’s test results to study the effect of time on sucrose movement rate.
4. Modifying procedures to assess sucrose concentration effects on diffusion rates through controlled time periods.
5. Drawing detailed plan diagrams of plant stems, highlighting vascular bundles and other tissue types.
6. Measuring vascular bundle lengths in photomicrographs and calculating their actual dimensions using magnification.
