FLASHCARD QUESTION
Front
Plasma Membrane Noun
[plaz-muh mem-breyn]
Back
Plasma Membrane
The semipermeable barrier surrounding a cell, controlling what enters and leaves; also known as the cell membrane.
Example: This diagram shows the plasma membrane is a flexible barrier with embedded proteins that control what substances can pass into or out of the cell.

FLASHCARD QUESTION
Front
Homeostasis Noun
[hoh-mee-oh-stey-sis]
Back
Homeostasis
The tendency of a system, such as a cell, to maintain a stable, balanced internal environment.
Example: This diagram shows a red blood cell delivering oxygen to body cells, a process that maintains stable oxygen levels, which is an example of homeostasis.

FLASHCARD QUESTION
Front
Semipermeable Adjective
[sem-ee-pur-mee-uh-buhl]
Back
Semipermeable
A property of a membrane that allows certain substances to pass through but prevents others from passing.
Example: This diagram shows a semipermeable cell membrane, which acts as a selective barrier, allowing certain molecules like water to pass through into the cell.

FLASHCARD QUESTION
Front
Phospholipid Noun
[fos-foh-lip-id]
Back
Phospholipid
A lipid molecule with a hydrophilic head and two hydrophobic tails that is the main component of cell membranes.
Example: This diagram shows how a phospholipid has a water-loving (hydrophilic) head and a water-fearing (hydrophobic) tail, causing them to form a lipid bilayer.

FLASHCARD QUESTION
Front
Hydrophilic Adjective
[hahy-droh-fil-ik]
Back
Hydrophilic
Describes molecules or parts of molecules that are attracted to, and can interact with or dissolve in, water.
Example: This diagram shows a cell membrane's phospholipid bilayer, where the round 'hydrophilic heads' face outwards because they are attracted to water.

FLASHCARD QUESTION
Front
Hydrophobic Adjective
[hahy-droh-foh-bik]
Back
Hydrophobic
Describes molecules or parts of molecules that repel or do not mix with water, often being nonpolar.
Example: This diagram shows that hydrophobic ('water-fearing') tails of molecules cluster together to avoid water, surrounding an oil droplet, a key principle in cell membrane formation.
7.
FLASHCARD QUESTION
Front
Phospholipid Bilayer Noun
[fos-foh-lip-id bahy-ley-er]
Back
Phospholipid Bilayer
The double layer of phospholipid molecules that forms the basic structure of a plasma membrane, with tails facing inward.
Example: This diagram shows the phospholipid bilayer as two layers of molecules, forming the basic structure of the cell membrane, which also contains various proteins.
