This picture represents what type of active cell transport?
The concentration of red molecules outside the cell is higher than the concentration inside the cell. The red molecules cannot penetrate the cell. What will happen to the cell?
Water will leave the cell, and the cell will shrink. The solution is isotonic.
Water will enter the cell, and the cell will expand. The cell is isotonic.
Water will enter the cell, and the cell will expand. The cell is hypertonic.
Water will leave the cell, and the cell will shrink. The solution is hypertonic.

Facilitated diffusion
Osmosis
Diffusion
Which type of transport does not use energy to transport substances?
Active transport
Passive transport

sugar
water
calcium ions
What macromolecule is embedded into the lipid bilayer and helps to transport molecules?
Carbohydrate

What is the function of carbohydrates in the cell membrane?
The make up the majority of the cell membrane.
They act as channels for substances to pass through.
They act as name tags for the cell which is important for cell recognition and interaction.
They are not found in the cell membrane.
What type of molecules CANNOT easily diffuse through the cell membrane and would need a protein to help them?
Small Molecules
Large Molecules

You bought some fresh flowers from the store but they started to look wilted. Once you placed them in a vase full of water, the leaves and stems began to swell again. What process is responsible for this swelling?
Photosynthesis
Osmosis
Diffusion
Active Transport
You got your wisdom teeth removed and the doctor told you to rinse your mouth with salt water. Why?
The salt water is a hypertonic solution, and the swollen cells in Devin's mouth will release water through osmosis.
The salt water is a hypotonic solution, and the swollen cells in Devin's mouth will take in water through osmosis.
The salt water is a hypotonic solution, and the swollen cells in Devin's mouth will release water through diffusion.
The salt water is a hypertonic solution, and the swollen cells in Devin's mouth will take in water through diffusion.

particles from high to low concentration
What is the primary role of cholesterol in the cell membrane?
To provide energy for the cell.
To stabilize the membrane's fluidity.
To act as a channel for molecules.
This picture is a representation of what type of transport?
Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.
Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

osmosis
active Transport
facilitated diffusion
diffusion
Students are observing particles moving with the concentration gradient in a lab investigation. Which type of transport are they observing? (check all that apply)
using pumps to move things quickly
passive transport
osmosis
endocytosis
This picture shows molecules of red dye that have moved. What is this type of movement called?
Osmosis; the water molecules are moving from high concentration to low
Diffusion; the dye molecules are moving from low to high concentration
Diffusion; the dye molecules are moving from high to low concentration.
Facilitated diffusion; because the molecules are moving through a protein channel.
