Osmosis Flashcards
What is osmosis?
Osmosis is when Solvent molecules go from low solute concentration to high solute concentration through a semi-permeable membrane until it’s the same concentration
Water moves into plants from the soil and exists through the leaves. Explain how water moves from the soil into the root
When water is poured into the soil, the soil will have a low solute concentration, and the roots will have a higher solute concentration, so the water will move from a low solute concentration into a high solute concentration through a semi-permeable membrane, using osmosis.
What would happen if you put an animal cell in pure water?
Water enters the cell as a result of osmosis, and makes the cell expand. Since animal cells do not have a cell wall, when too much of this water enters to make the concentration of water on both sides even, the animal cell may eventually burst and die out.
Hypertonic/Hypotonic/Isotonic in the red blood cell
Hypertonic: Shrink
Hypotonic: Expand
Isotonic: Same Size
Hypertonic/Hypotonic/Isotonic in the plant cell
Hypertonic: Shrink(PLASMOLYSIS)
Hypotonic: Expand(TURGID)
Isotonic: Same Size
What happens when a red blood cell is placed in a hypotonic solution?
The solvent will move from low solute concentration in the hypotonic solution to high solute concentration inside the cell through a semi-permeable membrane through the process of osmosis. The cell will expand and sometime it will burst.
What happens when a plant cell is placed in a hypotonic solution?
The solvent will move from low solute concentration in the hypotonic solution to high solute concentration inside the cell through a semi-permeable membrane through the process of osmosis. The cell expands (in a process called cytolysis) and becomes turgid because of the cell wall protecting the cell from bursting.
What happens when a red blood cell is placed in a hypertonic solution?
The solvent molecules will move from low solute concentration inside the cell to high solute concentration to outside the cell in the hypertonic solution through a semi-permeable membrane through the process of osmosis. The cell shrinks.
What happens when a plant cell is placed in a hypertonic solution?
The solvent molecules will move from low solute concentration inside the cell to high solute concentration in the hypertonic solution through a semi-permeable membrane through the process of osmosis. The cell shrinks through plasmolysis.
What happens when a red blood cell is placed in an isotonic solution?
The cell reaches equilibrium and stays the same size. The concentrations will be equal.
What happens when a plant cell is placed in an isotonic solution?
The cell reaches equilibrium and stays the same size. The concentrations will be equal.
