100
All cells are surrounded by it.
What is a cell membrane?
100
This term describes the free movement of small, non-polar molecules across the cell membrane.
What is passive transport?
100
The act of materials moving against the concentration gradient.
What is active transport?
100
Osmosis is the diffusion of this type of molecule across a cell membrane.
What is a water molecule?
100
This 19th century Austrian priest is known as "the father of genetics."
Who is Gregor Mendel?
200
The barrier surrounding cells is made up of a double layer of lipids, also known as this.
What is a lipid bilayer?
200
Particles are moving across a membrane equally in both direction, no net change.
What is equilibrium?
200
This is required to move molecules to a high concentration.
What is energy?
200
These special channels facilitate the movement of water molecules across the cell membrane.
What are aquaporins?
200
This structure made mostly of protein surrounds plant, fungi, and prokaryotic cells.
What is a cell wall?
300
These structures form channels and pumps to move molecules into and out of the cell.
What is a membrane protein?
300
The net movement of particles from a HIGH to LOW concentration.
What is diffusion?
300
Forcing contents out of a cell by fusing it to the cell membrane.
What is exocytosis?
300
This state of a molecule prevents it from being able to directly pass through the cell membrane. (Not the bear kind)
What is polar?
300
The 3rd president of the United States.
Who is Thomas Jefferson?
400
Some substances can cross the cell membrane freely while others are selectively prohibited.
What is semi-permeable?
400
This specialized type of passive transport only applies to water molecules.
What is osmosis?
400
These use ATP to "pump" ions across the cell membrane.
What are protein pumps?
400
In a hypertonic solution, the solute concentration is greater outside of the cell. The net movement of water molecules causes the cell to do this.
What is shrink?
400
Ms. Spatter's first name.
What is Alexandra?
500
This binomial term is used to describe the dynamic nature and composition of the cell membrane.
What is a fluid mosaic?
500
Facilitated transport is best for these types of molecules.
What are large and polar molecules?
500
The analogy that Ms. Spatter used when describing active transport.
What is walking on an escalator traveling in the opposite direction?
500
In plants, this term describes the pressure of the cell membrane pushing against the cell wall.
What is turgor pressure?
500
The name of this molecular police officer.
Who is Osmosis Jones?
