This organelle is found in both plant and animal cells and controls the movement of substances in and out of the cell
What is the cell membrane?
This organelle is found in plant but not animal cells and provides protection and structure for the cell.
What is the cell wall?
Pressure is calculated by dividing force by this quantity.
What is area?
Diffusion is the movement of molecules from an area of ______ concentration to an area of ______ concentration.
high to low
This force pulls objects toward Earth.
What is gravity?
This organelle is a powerhouse of the cell.
What is a mitochondrion?

What is a vacuole and water?
Snowshoes reduce pressure by increasing this.
What is surface area?
Water moves across a membrane by a special type of diffusion called what?
What is osmosis?
This force opposes motion when two surfaces rub against each other.
What is friction?
This a jelly-like substance that fills the cell and helps it hold its shape.
What is cytoplasm?
This cell is circular in shape and does not have a cell wall.
What is an animal cell?
Two students push with the same force. The student using a smaller contact area produces more of this.
What is pressure
Diffusion is a type of this kind of transport that does not require energy.
What is passive transport?
When you push a shopping cart, you are applying this type of force.
What is an applied force?

What is 400 Pa?
The main goal of diffusion is to reach this balanced state.
What is equilibrium?
A book resting on a table does not fall through because of this upward force from the table.
What is the normal force?
This power making organelle is only in plants and uses sunlight for energy.

What are glucose and oxygen?
The unit of pressure is named after this scientist and is abbreviated Pa.
Who is Blaise Pascal?
If molecules move against the concentration gradient, energy is needed — this is called what?
What is active transport?
A force of 50 N acts to the right and another force of 30 N acts to the left. This is the net force on the object.
What is 20 N to the right?
