Worksheet time: 10mins
In simple diffusion, how do particles move across a membrane?
From an area of low concentration to high concentration.
From an area of high concentration to low concentration.
Only with the help of carrier proteins.
By using ATP energy.
What is the main structural component of the cell membrane that allows certain substances to pass through?
A single layer of proteins.
A phospholipid bilayer.
A carbohydrate chain.
A rigid cell wall.
Which statement accurately describes facilitated diffusion?
It requires ATP to move particles against their concentration gradient.
It moves particles from a low concentration to a high concentration.
It uses channel or carrier proteins to move particles with the concentration gradient.
It only transports solid particles into the cell.
What is the primary energy source required for active transport to move substances across the cell membrane?
Glucose
Oxygen
ATP
Carbon dioxide
Which process involves the cell engulfing larger objects by forming a vesicle around them?
Exocytosis
Facilitated diffusion
Endocytosis
Simple diffusion
Tap on all the pictures of ACTIVE transport.
If the molecules move through PASSIVE TRANSPORT in this diagram which side are the molecules going to?
Cells can use (a) to bring in ions or molecules when there is already a higher concentration of the ions or molecules inside the cell than outside the cell. An Example of this would be (b)
Active transport of solutes across the cell membrane requires (a) because molecules are moved against the (b) , meaning from (c) concentration . For example, when mangrove trees use salt (d) to secrete salt from their roots.
