Let's solve the diffusion worksheet step by step using the provided word box:
Word Box:
low, energy, facilitated, high, equal, simple, evenly

Step 1: Understand the concept of diffusion
Diffusion is the movement of molecules from an area of
high concentration to an area of
low concentration until they are
evenly distributed. This process occurs naturally and does not require energy input.
There are two main types:
-
Simple diffusion: Movement of small molecules directly through the membrane.
-
Facilitated diffusion: Movement through protein channels (still passive, no energy needed).
In the diagram:
- A drop of copper sulfate is added to a beaker of water.
- Initially, the copper sulfate is concentrated in one area (high concentration).
- Over time, it spreads out until the solution becomes uniform (equal concentration throughout).

Now fill in the blanks:
> Diffusion is the process by which molecules move from a region of
high concentration to region of
low concentration until the particles are
evenly distributed. It is a natural, random process that does not require
energy input.
Simple and
facilitated diffusion are the two types of diffusion. The part of the solution of the beaker where copper sulfate is added has a
high concentration of copper sulfate molecules than other parts. Diffusion continues until the concentration becomes
equal throughout the solution.

✔ Final Answer with explanations:
1.
high – Molecules move from high concentration to low.
2.
low – They move toward areas of lower concentration.
3.
evenly – Eventually, particles spread out uniformly.
4.
energy – Diffusion is passive; no energy (ATP) is needed.
5.
Simple – One type of diffusion.
6.
facilitated – The other type, involving carrier proteins.
7.
high – The spot where copper sulfate is added has more molecules.
8.
equal – Diffusion stops when concentrations are balanced.

✔️ Completed Sentence:
> Diffusion is the process by which molecules move from a region of
high concentration to region of
low concentration until the particles are
evenly distributed. It is a natural, random process that does not require
energy input.
Simple and
facilitated diffusion are the two types of diffusion. The part of the solution of the beaker where copper sulfate is added has a
high concentration of copper sulfate molecules than other parts. Diffusion continues until the concentration becomes
equal throughout the solution.
This matches both the scientific concept and the visual representation in the image.
