|
|
What is cytoplsmic streaming?
|
The movement of cytoplasm in such a way as to distribute cytoplasmic nutrients in different parts of the cell where it is needed
|
|
|
What is solute
|
a component of a solution
|
|
|
What is solvent
|
the dissolving substance
|
|
|
What is the solution
|
a homogeneous mixture formed by a single phase of liquid
|
|
|
What is concentration gradient
|
A gradual change in the concentration of solutes in a solutions as a function of distance through a solution
|
|
|
What is osmosis?
|
The net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on two sides of a membrane
|
|
|
What is Tonicity?
|
The measure of the osmotic pressure gradient of two solutions separated by a semipermeable membrane
|
|
|
What is a hypotonic solution
|
Refers to any solution which has less solute. The cell will increase it's fluid intake
|
|
|
What is hypertonic solution
|
Water diffuses out of the cell, and the cytoplasm shrinks and gets more concentrated.
|
|
|
What is an isontic solution
|
Nothing. There is no difference between concentration's gradient and so no net flow of water from cytosol [liquid part of cytoplasm] to the solution in which cell is immersed occurs
