Flaccid Cells and Plasmolysis

• What type of cell is shown on the left of the image?

  Flaccid cell
• What are the stages of plasmolysis shown in the image?

  • Normal cell
  • Cells showing contraction of cytoplasm
  • Plasmolysed cell
  • Plasmolysing solution
• What visual difference is shown in the image between flaccid and turgid cells?

  Flaccid cells have shrunken cytoplasm
• What is the relationship between solute and solvent in a concentrated solution?

  • High amount of solute
  • Low amount of solvent
  • Results in a strong mixture
• What happens to the cytoplasm and vacuole in a flaccid cell?

  They become shrunken
• What does the term "flaccid" mean in relation to plant cells?

  It means limp and floppy
• What is the name of the solution that causes plasmolysis?

  Plasmolysing solution
• What is the name of the process shown in the image?

  Plasmolysis
• What happens to water in a plant cell in a concentrated solution?

  Water moves out of the cell
• What is the purpose of plasmolysis?

  To cause the cell wall to contract and separate from the cell membrane
• If a plant cell is placed in a hypertonic solution, what would happen?

  The cell would undergo plasmolysis
• What is the initial state of a cell before it loses water?

  A turgid cell
• What are the key differences between a normal cell and a plasmolysed cell?

  • Normal cell: Cell wall and membrane are in close contact
  • Plasmolysed cell: Cell wall and membrane have separated due to loss of water
• What is the consequence of water loss on the vacuole?

  The vacuole shrinks dramatically
• What is the final stage of plasmolysis?

  Cytoplasm shrinks to center
• What happens to the cytoplasm when water leaves the cell through osmosis?

  The cytoplasm shrinks and pulls away
• What is plasmolysis?

  Separation of cell membrane from cell wall
• What are the stages of plasmolysis?

  1. Early phase: Cell membrane starts contracting
  2. Plasmolysis: Membrane completely separates from cell wall
  3. Final stage: Cytoplasm shrinks to center
• What is the name of the process shown in the image?

  Plasmolysis
• What are the stages of plasmolysis shown in the image?

  • Normal cell
  • Cells showing contraction of cytoplasm
  • Plasmolysed cell
  • Plasmolysing solution
• What is happening to the water in the turgid cell?

  Water is entering the cell
• What is the name of the process shown in the image?

  Plasmolysis
• What is the purpose of plasmolysis?

  To cause the cell wall to contract and separate from the cell membrane
• How is cell turgidity related to osmosis?

  Turgidity results from water entering via osmosis
• How does the cell wall change during plasmolysis?

  • The cell wall contracts and separates from the cell membrane
  • This is caused by the loss of water from the cell
• What is the name of the process shown in the image?

  Plasmolysis
• How does the cell wall change during plasmolysis?

  • The cell wall contracts and separates from the cell membrane
  • This is caused by the loss of water from the cell
• If a plant cell is placed in a hypertonic solution, what would happen?

  The cell would undergo plasmolysis
• What happens to a plant cell in a concentrated solution?

  The plant cell becomes flaccid
• What is the purpose of plasmolysis?

  To cause the cell wall to contract and separate from the cell membrane
• What are the stages of plasmolysis shown in the image?

  • Normal cell
  • Cells showing contraction of cytoplasm
  • Plasmolysed cell
  • Plasmolysing solution
• How does the cytoplasm change during plasmolysis?

  The cytoplasm shrinks as the membrane detaches
• How does a flaccid cell appear compared to a turgid cell?

  It appears soft and floppy
• What is the name of the cell state shown in the middle image?

  Flaccid
• What appearance does a cell have when it becomes flaccid due to water loss?

  A limp, flaccid appearance
• What is the name of the solution that causes plasmolysis?

  Plasmolysing solution
• What is a concentrated solution?

  A strong, intense mix of solute and solvent
• What are the characteristics of flaccid and turgid cells?

  • Flaccid cells:
  • Limp and soft
  • Shrunken cytoplasm and vacuole
  • Turgid cells:
  • Firm and swollen
  • Full vacuole and cytoplasm
• What are the key differences between a normal cell and a plasmolysed cell?

  • Normal cell: Cell wall and membrane are in close contact
  • Plasmolysed cell: Cell wall and membrane have separated due to loss of water
• In osmosis, where does water move from and to in a concentrated solution?

  From higher concentration to lower concentration
