Materials: Red onion Elodea Micro forceps Glass slides Cover slips KimWipes Droppers Tally counters Compound microscopes with 4X and 10X objectives Distilled water 15% NaCl and 1M NaCl solutions Gloves Methods: Part I. Red Onion Cells Red onion cells contain a flavonoid pigment called anthocyanin, which gives the onion its purplish color. The same pigment gives petunias their deep purple color. This pigment allows us to visualize what happens to the water content in a cell when ...

BSC1005 Lab Final Guaranteed Success Osmosis specifically refers to the transport process responsible for the movement of water in and out of cells. Among the methods for transporting molecules across a cell membrane, Passive Transport is the only one that does not require energy. A hypertonic solution has a higher concentration of dissolved solutes compared to the outside of the cell, while a hypotonic solution has a lower concentration of dissolved solutes relative to the outside...
