Document Summary

Protective layer against dehydration and aids in adherence to surfaces, protects cell from the environment. Resistance to osmotic stress/ lysis, helps maintain shape, protects the cell from toxic substances. Retains the cytoplasm and separates the cell from the environment, Contain transport systems used for nutrient uptake, waste excretion, and protein secretion, Location of a variety of crucial metabolic processes including respiration, photosynthesis, lipid synthesis, and cell wall synthesis, It contains special receptor molecules that enable detection of and response to chemicals in the surroundings protects against antibodies. Extra set of genetic information, gives cell the ability to adapt to stressful environments. Allows cell to store metal there so they can orient themselves along the magnetic pole. Attaches cell wall (peptidoglycan) to the cell membrane (in gram +) Stabilizes the height and weight of the tower of lta, keeps it from falling over. Braun"s lipoprotein attaches the cell wall (peptidoglycan) to the outer membrane (in gram -)
