Organelles
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
Kaylee's favourite fish
What is a pufferfish?
This organelle is a powerhouse of the cell.
What is a mitochondrion?
Plant cells have a larger one of these because they need more storage of what.
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?
Eric's favourite branch of science.
What is physics?
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?

This small organelle is often referred to as the factory worker making proteins
What are ribosomes?
The main reactants of photosynthesis are these three things.
What are carbon dioxide, water, and sunlight?
A force of 200 N acts on an area of 0.5 m². This is the pressure produced.
What is 400 Pa?
The main goal of diffusion is to reach this balanced state.
What is equilibrium?
Kaylee's regular bubble tea sugar level (0%, 30%, 50%, 70%, 100%)
This power making organelle is only in plants and uses sunlight for energy.
The main reactants of cellular respiration are these two substances.
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?
