![**Understanding Osmosis in Plant and Animal Cells**
This educational module illustrates the effects of osmosis on plant and animal cells in different tonic environments. Follow along to understand how cells respond under isotonic, hypertonic, and hypotonic conditions.
**Instructions:**
Mark the flow of water with an arrow for cells placed in solutions of differing tonicity. Indicate the resulting changes to both plant and animal cell shapes under each condition.
### (a) Environment: Isotonic
**Diagram Explanation:**
- Isotonic Condition: The solute concentration outside the cell is equal (isotonic) to the inside of the cell.
- Illustration shows an equilibrium, suggesting no net movement of water.
**Expected Changes:**
- Plant Cell Shape: [No Change]
- Animal Cell Shape: [No Change]
### (b) Environment: Hypertonic
**Diagram Explanation:**
- Hypertonic Condition: The solute concentration outside the cell is higher (hypertonic) than the inside of the cell.
- The illustration demonstrates water molecules moving out of the cell, denoted by arrows pointing outward.
**Expected Changes:**
- Plant Cell Shape: [Plasmolysis] (The cell membrane pulls away from the cell wall as water exits.)
- Animal Cell Shape: [Crenation] (The cell shrinks and appears wrinkled as water exits.)
### (c) Environment: Hypotonic
**Diagram Explanation:**
- Hypotonic Condition: The solute concentration outside the cell is lower (hypotonic) than the inside of the cell.
- The illustration shows water molecules moving into the cell, represented by arrows pointing inward.
**Expected Changes:**
- Plant Cell Shape: [Minor Swelling] (The cell swells but is protected from bursting by its cell wall.)
- Animal Cell Shape: [Swelling and Lysis] (The cell may swell and potentially burst as it takes in excess water.)
Explore these conditions to gain a deeper understanding of cellular osmoregulation. Use this knowledge to predict cell behavior in varying environmental contexts.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fce91b2b5-641d-42b8-b984-886071369623%2Fc1ddec5f-ccbd-4088-b080-129fb1783069%2Fgixvg7_processed.png&w=3840&q=75)
