Step-by-step solution for: Diffusion & Osmosis Worksheet by Flawsome Learning worksheets library
It looks like you've uploaded an image of a worksheet about osmosis, but the image is not visible to me. However, based on your description and the text provided in your message, I can help you solve the problem and explain the concept.
Let’s go through what appears to be on the worksheet and solve it step by step.

Definition:
*Osmosis is a form of ________ that involves the movement of H₂O molecules from an area of ________ concentration to an area of ________ concentration. This helps to ________ out the difference inside of a cell.*
Words to Use:
- water
- low
- balance
- high
- diffusion
---
Let’s complete the definition using the correct terms:
> Osmosis is a form of *diffusion* that involves the movement of H₂O molecules from an area of *low* concentration to an area of *high* concentration. This helps to *balance* out the difference inside of a cell.
✔ Explanation:
- Osmosis is a type of diffusion (passive transport) specifically for water.
- Water moves from areas of low solute concentration to areas of high solute concentration.
- This movement helps balance the concentration on both sides of the membrane.

There are two diagrams labeled (1) and (2) showing circles representing water molecules and solute molecules. There's also a KEY FOR DIAGRAM with three questions.
Let’s interpret and answer them based on standard osmosis principles.
---
#### 📌 Diagram 1: Side A vs. Side B
Assume:
- Side A has fewer solute molecules → lower concentration
- Side B has more solute molecules → higher concentration
- The membrane is selectively permeable (allows water, not solutes)
##### Question 1:
> "Draw in the molecule on the right-hand side of the selectively permeable membrane, showing a lower concentration of water molecules compared to the left-hand side."
✔ Answer:
On the right side (higher solute concentration), there should be fewer water molecules drawn than on the left. This is because solutes attract water, reducing the relative number of free water molecules.
So, draw fewer dots (water molecules) on the right side than on the left.
---
##### Question 2:
> "Draw an arrow to show the direction of the concentration gradient."
✔ Answer:
The concentration gradient for water goes from high water concentration to low water concentration.
- Water moves from Side A (left) → Side B (right)
- So, draw an arrow pointing from left to right across the membrane.
This shows water moving toward the area with more solutes (higher solute concentration).
---
##### Question 3:
> "How do we draw in water molecules on both sides of the selectively permeable membrane to show that equilibrium has been reached due to osmosis?"
✔ Answer:
At equilibrium, the number of water molecules on both sides will be equal (or balanced), even though solutes may still be unevenly distributed.
But since the membrane is selectively permeable, solutes cannot cross — so water moves until the concentration gradient is balanced by pressure or equal water distribution.
To show equilibrium:
- Draw equal numbers of water molecules on both sides.
- The solute molecules remain unchanged (can’t move).
- No net movement occurs.

1. Fill-in-the-blank sentence:
> Osmosis is a form of diffusion that involves the movement of H₂O molecules from an area of low concentration to an area of high concentration. This helps to balance out the difference inside of a cell.
2. Diagram 1:
- Fewer water molecules on the right side (high solute).
- Arrow pointing from left to right (direction of water movement).
- At equilibrium: Equal number of water molecules on both sides.
---
- Osmosis = passive movement of water across a semi-permeable membrane.
- Driven by concentration gradient of solutes.
- Water moves from low solute → high solute concentration.
- Goal: Balance the concentrations (achieve equilibrium).
---
If you can provide the actual diagram or clarify how the solutes and water are arranged in your image, I can give even more specific guidance. But this should fully cover the typical osmosis worksheet like the one described!

🧠 Concept Recap: Osmosis
- Osmosis = passive movement of water across a semi-permeable membrane.
- Driven by concentration gradient of solutes.
- Water moves from low solute → high solute concentration.
- Goal: Balance the concentrations (achieve equilibrium).
