2. Elodea: Focus on the chloroplasts and the plasma membrane within the cell: describe what happened to the chloroplasts when the salt solution was applied to the Elodea cells and explain what happened in terms of osmosis. What happened to the chloroplasts when the fresh water was placed on the cells? What differences in the appearance of the cell are evident? What has caused these differences?

Step 1
As a result, water moves out of the cell through the process of osmosis, causing the cell to lose water and shrink. This leads to the plasma membrane pulling away from the cell wall, a process known as plasmolysis. The chloroplasts within the cell may also become Show more…

Explain how contractile vacuoles in protists and central vacuoles in plant cells aid in the osmoregulation of cells. Explain how osmoregulation maintains water balance and allows organisms to control their internal solute composition/water potential. Describe the processes that allow ions and other molecules to move across membranes. Explain how membranes and membrane-bound organelles in eukaryotic cells compartmentalize intracellular metabolic processes and specific enzymatic reactions. Explain how internal membranes facilitate cellular processes. Explain how endosymbiosis resulted in the evolution of membrane-bound organelles. Describe how prokaryotes compartmentalize cellular reactions without membrane-bound organelles. Explain how internal membranes partition a eukaryotic cell into specialized regions. Describe the relationship between the functions of endosymbiotic organelles and their free-living ancestral counterparts.
