Cell Membrane Structure
This is the number of layers of phospholipids found in the cell membrane.
What is two?
What is water loving?
Water moves in & out of the cell at equal rates.
What is isotonic?
This type of transport does not require energy.
What is passive?
This is the basic unit of life.
What is a cell?
This is the main function of the cell membrane.
What controls what enters & leaves the cell?
This can cross the cell membrane very easily.
What are small molecules (carbon dioxide, oxygen)?
Water moves into the cell & causes the cell to swell.
What is hypotonic?
Movement of particles from high to low concentration.
What is simple diffusion?
Two or more different types of tissues working together describe this.
What are organs?
The cell membrane has this permeability.
What is selective permeability?
These molecules cannot cross the cell membrane very easily.
What are large or charged molecules (glucose, sodium ions)?
Water moves out of the cell & causes the cell to shrink.
In this type of transport, substances move from a low concentration to a high concentration.
What is active transport?
A group of organs working together to perform an important function describes this.
What is an organ system?
This bilayer makes up the cell membrane.
What is the phospholipid bilayer?
The movement of water across a cell membrane.
What is osmosis?
Tonicity involves this type of passive transport.
What is osmosis?
What is:
1) Simple diffusion
2) Osmosis
3) Facilitated Diffusion
This is the definition of homeostasis.
Describe the phospholipid head & tail.
What is hydrophilic head & hydrophobic tail?
This is what helps move large or charged ions move across the cell membrane?
What is a transport protein?
This is the goal of tonicity.
What is homeostasis (keep the inside of the cell stable).
Movement of particles from high to low concentration with the help of a protein.
What is facilitated diffusion?
List the order of cell organization from small to large.
What is cells --> tissues --> organs --> organ systems --> organisms?
