What is an isotonic solution?
An isotonic solution.
When a cell has something like glucose, ions, proteins and other substances!!!
When a cell is in a solution that has the same concentration of water and solutes as its cytoplasm!!!
It's an osmosis!!! :D
What allows some substances to pass while keeping others out in a plasma membrane?
selective permeability.
diffusion!!
selective probability!!!!
Algebra!!!! >_<
The net movement of particles from an area where there are many particles of the substance to an area where there are fewer particles of the substance
(a)
What is dynamic equilibrium?
the condition in which there is no movement but change :)
You. :O
the condition in which there is continuous movement but no overall change
I gave up writing this.
What moves needed substances or waste materials through the plasma membrane?
(a)
What is the phospholipid bilayer?

The phospholipids in the bilayer creating a "sea" in which other molecules can float in is a:
haiii!!!
polar heads!!!
carbohydrates
fluid mosaic model ^^
What is the diffusion of water across a selectively permeable membrane?
(a)
What is facilitated diffusion?
A form of transport that uses transport proteins to move other ions and small molecules across the plasma membrane
A form of transport that transports fatty acids through the cell membrane
A cell in a solution that has a lower concentration of solute
hypotonic solution
hypertonic solution
The secretion of materials at the plasma membrane
Endocytosis
Exocytosis
The movement of substances across the plasma membrane against a concentration of gradient is a(n) (a) transport
The process by which a cell surrounds a substance in the outside environment, enclosing the substance in a portion of the cell membrane
Endocytosis
Exocytosis
A (a) solution is when a cell is placed in solution that has a concentration of solute outside the cell that is higher than the inside
