Anatomy Lab Practical: Part 5
This flashcard set covers the principles of tonicity and its effects on cells, including how water moves across the plasma membrane in hypotonic, hypertonic, and isotonic solutions. It also introduces the four key phases of the cell cycle, essential for understanding cell growth and division.
What determines how water crosses the plasma membrane?
tonicity
Key Terms
What determines how water crosses the plasma membrane?
tonicity
Lower solute concentration than the cytosol
hypotonic
cell will gain water by osmosis and may swell or burst
Same solute concentration as the cytosol
isotonic
Higher solute concentration than the cytosol
hypertonic
cell will lose water and shrivel/shrink
What will the cell do when it is in a hypotonic solution?
cell will gain water by osmosis and may swell or burst
What will the cell do when it is in a hypertonic solution?
cell will lose water and shrivel/shrink
