How would you determine the best concentration of solutes to give a patient in need of fluids before you introduced the fluids into the patient's body?
Measure the tonicity or water potential of blood.
What solution has the greatest solute concentration?
Hypertonic
: The solution with the higher concentration of solutes.
Where is the solute concentration the greatest?
There is more solute in
the solution surrounding a cell than inside
, resulting in a greater amount of water (solvent) inside the cell. The more solute, the less solvent (i.e. water).
What is high solute concentration?
Hypertonic
: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.
What factors determine the rate and direction of osmosis quizlet?
the concentration of water
determines the direction in which molecules will move during osmosis. the point at which water molecules enter and leave a cell at the same rate. the concentration inside and outside of the cell are equal.
What is the concentration of solute inside the cell?
The concentration of the solute in the solution is
the same as the concentration inside the cell
. 4.
When the concentration of solute inside and outside a cell is the same the cell has reached?
If a cell is placed in an
isotonic solution
, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.
What is the role of solute concentration?
The definition of solute concentration is the amount of solutes/particles that are dissolved in a solution. … This is defined as
the ability of a solute to be dissolved in a solvent
. If the solute is small, it can be dissolved quicker in a solvent.
Why does water move towards high solute concentration?
Very simple explanation for osmosis is the concentration of water explanation – water in pure water is
simply more concentrated than water in solutions because the solute has to take up some room in the solution
.
What does lower solute concentration mean?
Osmosis relates to solute concentration in that when solute concentration is lower,
the concentration of solvent is higher
, and when the solute concentration is higher, the concentration of solvent is lower.
What factors determine the rate and direction of osmosis?
Concentration gradient
– The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent. Light and dark – They are also factors of osmosis; since the brighter the light, the faster osmosis takes place.
How do you determine the direction of osmosis?
The net flow of solvent through a semipermeable membrane is called osmosis (from the Greek osmós, meaning “push”). The direction of net solvent flow is
always from the side with the lower concentration of solute to the side with the higher concentration
.
What do we call the movement of water with the concentration gradient?
| Term Meaning | Osmosis The net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration | Tonicity The ability of an extracellular solution to make water move into or out of a cell by osmosis |

When a cell is in a solution where the concentration of solute is the same?
| A B | when the concentration of the solute is the SAME throughout a system, the system has reached equilibrium | particles tend to move from an area where they are MORE concentrated to an area where they are LESS concentrated, is a process of diffusion |

What is a hypertonic solution Class 9?
If the medium surrounding the cell has a lower water concentration than inside the cell
, i.e., if the solution is highly concentrated, then the cell will lose water through osmosis. Such concentrated solution is called Hypertonic solution.
Is turgor a pressure?
Turgor,
Pressure exerted by fluid in a cell
that presses the cell membrane against the cell wall. Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.
