Cell Transport Practice

Match

Match the following aspects of the cell membrane.

• Acts as channels and receptors

• Helps the cell to recognize its surroundings

• The cell membrane is mostly made out of this molecule.

Selectively permeable

Proteins

Carbohydrates

Phospholipids

• Selectively permeable

• Proteins

• Carbohydrates

• Phospholipids

Does not require energy to move a molecule from high to low concentration. (DOWN the concentration gradient)

concentration.

Multiple Choice

______ occurs when any particle moves across the membrane from high to low concentration.

• Active transport

• Osmosis

• Diffusion

• Facilitated diffusion

Hotspot

Choose the image that represents facilitated diffusion.

Osmosis is the diffusion of water. (water moving down the concentration gradient)

​

Osmosis

Dropdown

The diffusion of water is called ​

Select answer

Water will move out of the cell, causing the cell to shrivel. Water moves from higher to lower concentration out of the cell.

​Cell in really salty water.

Water moves in the cell due to osmosis. Water is moving from higher concentration (the pure water) to lower concentration. The cell swells.

​

​Cell in pure water.

Cell stays the same size. The same amount of water enters and leaves the cell.

​

Cell in solution with equal concentration.

Multiple Choice

If an animal cell is placed in very salty water, it will ______ due to water moving out of the cell.

• shrivel

• swell

• burst

​HINT

For the next few slides, remember.....if a solution is 15% solute, then it must be 85% water. If it's 18% solute, then it is 82% water.

Multiple Choice

What will happen to the cell in this solution?

• It will swell and possibly burst.

• It will shrivel.

• It will remain the same size.

Multiple Choice

In the hypotonic solution, the cell will ____ due to osmosis.

• shrivel

• swell

• remain the same size

The movement of molecules across the membrane with energy, against the concentration gradient.

​

Active transport

Drag and Drop

Active transport involves moving molecules across the cell membrane from ​

low

high

A cell engulfs and brings in materials. This is a type of active transport because it requires energy to move such large amounts of materials.

​

​Endocytosis

The cell uses energy to release or secrete materials. This is also active transport because it requires energy.

​

​Exocytosis

You will answer questions about all cell transport to practice!

NOW.....

Multiple Choice

A process for removing large quantities of toxins and waste from the cell is

• exorcism
• exocytosis
• endocytosis
• endoplasmic reticulum

Multiple Choice

What does it mean that a cell membrane is, "selectively or semi-permeable?"

• It allows all substances in
• It allows some substances in but not others
• It allows nothing in

Multiple Choice

Active transport requires ______, moves materials from __________________, and goes _______ the concentration gradient.

• No energy, low to high, against
• ATP, high to low, with
• ATP, low to high, with
• ATP, low to high, against

Match

Match the following

The movement of water across the cell membrane

Bringing in large materials through the cell membrane into a vacuole.

Moving larger amounts or large quantities of materials through the cell membrane

• When molecules passively cross the plasma membrane through the phospholipid bilayer

• When molecules passively cross the plasma membrane through a channel protein

• The movement of water across the cell membrane

• osmosis
• facilitated diffusion
• active transport

Multiple Choice

What type of transport is shown in the diagram?

• Ion pump

• Facilitated diffusion

• Na/K pump
• Carrier Protein
• Exocytosis
• Endocytosis

Multiple Choice

if you put a plant in salt water it will ...
