Endocytosis is when the cell takes in large materials or liquids and exocytosis is when it leaves.
What is the difference between endocytosis and exocytosis?
100
Is the package that the cell comes in. It controls what comes into and goes out of the cell.
What is function of the cell membrane?
100
In a isotonic solution , water moves into and out of a cell at equal rates.
What is an isotonic solution?
100
A double layer of phospholipids.
What is the cell membrane made up of?
100
Well of course MS. G!!!!!!=)
Who is the best teacher ever??
200
It is a type of endocytosis in which the cell membrane grows out to surround large particles.
What is phagosytosis?
200
Its a protein that detects a signal and acts because of it.
What is a receptor?
200
When the cell has a higher concentration of water than the surrounding fluid.
What is a hypertonic solution?
200
No, because not all signals go by. Certain molecules blind a receptor.
Do cells respond to every signal?
200
yes saira and angelica its WILLIAM LEVY. lol!
who is the hottest cuban ever?
300
ATP
What supplies the energy needed for active transport?
300
This means that it allows some materials, but not all, to cross it, or permeate it.
What does selective permeability mean?
300
When the cell has a lower concentration of water than the surrounding fluid.
What is a hypotonic solution?
300
A fluid mosaic model.
What is the cell membrane described as?
300
SAIRA!!!!!!!!!!!!!!!!!!! but we love you!=)
Who wines alot?
400
Active transport uses energy and passive transport doesn't.
What is the difference between active transport and pasiive transport?
400
tea bag, metal detector, window screen, etc.
What are some examples of semipermeable objects?
400
It is the difference in the concentration of a substence from one place to another.
What is the concentration gradient?
400
The "head" is polar.
The "tail" is non-polar.
In the phosphilipd, which is polar and which is non-polar?
400
CHRISTIAN!!!!!<3
Who does AIMEE love?
500
The movement of chemical substances, usually across the cell membrane, against a concentration gradient; requires cells to use energy.
What is the definition of active transport?
500
They are: a phosphate group, a glycerol, and two fatty acid chains.
What are the three parts of a phospholipid?
500
They are the same. Diffusion is the movement of molecules from a place of higher concentration to a place of lower concentration, but osmosis only refers to water.
What is the difference between diffusion and osmosis?
