The Cell Membrane's Job
The cell membrane is primarily made of these lipid molecules that arrange themselves into a bilayer.
What are phospholipids?
The heads of phospholipids interact with water because they are this type of molecule.
What is hydrophilic?
This type of protein binds to specific molecules outside the cell and triggers a response inside
What is a receptor protein?
High levels of this molecule can cause stiff membranes, impacting fluidity and transport
What is cholesterol?
What did one tectonic plate say when he bumped into the other?
Sorry! My fault.
This structure helps maintain the fluidity of the cell membrane and influences permeability.
What is cholesterol?
The tails of phospholipids avoid water because they are this type of molecule.
What is hydrophobic?
This protein helps identify the cell and can be used in immune response
What is a marker protein?
Too much cholesterol can lead to this health condition affecting arteries
What is atherosclerosis?
What did the biologist wear to impress his date?
Designer genes.
The cell membrane is sometimes called this because it is constantly changing and has various molecules embedded in it.
What is the fluid mosaic model?
This special property of water allows it to form droplets and move through narrow spaces due to its molecules sticking together.
What is cohesion?
This protein aids in moving substances through the membrane by changing shape
What is a carrier protein?
This organ is responsible for producing and regulating insulin.
What is the pancreas?
What year was HNS built?
1960
This process allows certain large molecules like glucose to pass through the membrane with the help of a protein but without using energy.
What is facilitated diffusion?
Water is often called this because it can dissolve more substances than any other liquid.
What is the universal solvent?
These proteins can act like doors, helping large or charged molecules enter and exit the cell
What are transport proteins?
Unlike plants, animal cells do not have this outer structure, which provides extra support and protection.
What is a cell wall?
What kind of tree can be placed into your hand?
A palm tree.
This process allows certain large molecules like glucose to pass through the membrane with the help of a protein but without using energy.

What is a cell wall?
What kind of hair does the ocean have?
Wavy hair.
