Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

their only purpose is to invade a host cell‚ reproduce and destroy the host cell in the process. Close to 99% of bacteria are beneficial with only a few that cause diseases. Life on earth could not exist without bacteria. Bacteria produce nearly half of the oxygen found in the atmosphere. Viruses have no cells‚ nucleus‚ cytoplasm or cell membrane. Viruses consist of tiny particles of nucleic acid enclosed by a coat of protein. Viruses are smaller than bacteria and can only be seen by an electron microscope
