It looks like you've uploaded an image of a worksheet titled
"Imaginary in Cells" with a series of questions related to cell biology, specifically focusing on
cellular respiration,
photosynthesis, and the
flow of energy and matter in cells.
Since I can't view images directly, I’ll need you to describe the content or provide the text from the worksheet. However, based on what’s visible in your description (e.g., "Model 1: Movement of Water In and Out of Cells", a diagram of a cell, and questions about osmosis), it seems this is likely about
osmosis and water movement across cell membranes.
Let me help you solve it step by step — but first, I’ll assume the worksheet includes:
---
Model 1: Movement of Water In and Out of Cells
A diagram showing:
- A cell with a semipermeable membrane.
- Concentrations of solutes inside and outside the cell.
- Arrows indicating the direction of water movement.

Common Questions on Such a Worksheet:
####
1. What happens to the cell when placed in a hypotonic solution?
-
Answer: Water moves into the cell (by osmosis) because the external solution has a lower solute concentration than the inside of the cell.
-
Result: The cell swells; in animal cells, it may burst (lyse); in plant cells, it becomes turgid.
####
2. What happens in a hypertonic solution?
-
Answer: Water leaves the cell (moves out) because the external solution has a higher solute concentration.
-
Result: Cell shrinks (crenation in animal cells, plasmolysis in plant cells).
####
3. What happens in an isotonic solution?
-
Answer: No net movement of water — equal solute concentrations inside and outside the cell.
-
Result: Cell maintains normal shape.

Example Question & Solution:
>
Question: If a red blood cell is placed in a solution with a higher concentration of salt than inside the cell, what will happen?
>
Answer: The solution is
hypertonic relative to the cell. Water will move
out of the cell by osmosis, causing the cell to
shrink and become
crenated.

Key Concepts to Remember:
-
Osmosis: Movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
-
Solute concentration determines direction of water flow.
-
Tonicity describes how a solution affects a cell:
-
Hypotonic → water enters → cell swells
-
Hypertonic → water exits → cell shrinks
-
Isotonic → no net movement → cell unchanged

If you can
type out the exact questions or
describe the diagram and tasks from the worksheet, I can give you
precise answers and explanations tailored to your assignment.
For now, here’s a general summary of how to approach such problems:
✔ Step 1: Identify the solute concentration inside vs. outside the cell.
✔ Step 2: Determine the tonicity of the external solution.
✔ Step 3: Predict the direction of water movement.
✔ Step 4: Describe the effect on the cell (swell, shrink, burst, etc.).
