Question: Saved Help 5 Ng Tonicity Of Red Blood Cells, If The Solution Became Transparent After Adding Blood Cells, You Could Assume Ble Choice
The Solution Was Hypotonic And The Cells Had Burst
. The Solution Was Hypotonic And The Cells Had Remained Intact.
When testing tonicity of red blood cells if the solution became opaque after adding blood cells you could assume quizlet?
When testing tonicity of red blood cells, if the solution became opaque after adding blood cells, you could assume:
You could determine that the cells remained intact
, but you could not determine whether the solution was isotonic or hypertonic without looking at the cells under the microscope.
What would happen to red blood cells if they were placed in a hypertonic solution?
When placing a red blood cell in any hypertonic solution,
there will be a movement of free water out of the cell and into the solution
. This movement occurs through osmosis because the cell has more free water than the solution.
When conducting the tonicity of red blood cells lab if you had chosen the hypothesis red blood cells placed in an isotonic?
When conducting the Tonicity of Red Blood Cells lab, if you had chosen the hypothesis, ‘Red blood cells placed in an isotonic solution
will draw the water out of the cells causing the cell volume to decrease
‘, what would you have seen when you looked under the microscope at the cells?
When examining tonicity in elodea cells it was important to view the cells immediately after creating your wet mount slide True or false?
When examining tonicity in Elodea cells, it was important to view the cells immediately after creating your wet mount slide. The
cell membrane shrank away from
the cell wall because the solution was hypertonic.
Which direction is the net movement of water when a cell is placed in a hypertonic solution quizlet?
Which direction will water move if a cell is placed in a hypertonic solution? Why?
Water will leave the cell
because the outside has a greater solute concentration. Water will continue to leave until the solute concentration of the inside and outside are equal.
What occurs when a red blood cell is placed in an isotonic solution quizlet?
If red blood cells are immersed in an isotonic solution (0.85% sodium chloride solution),
water molecules flow across the membrane at the same rate in both directions
. There is no net movement of water molecules across the membrane. The red blood cells maintain their shape.
Does hypertonic shrink or swell?
A hypotonic solution causes a cell to swell, whereas a
hypertonic solution causes a cell to shrink
.
What is a hypertonic solution example?
Hypertonic solutions have a higher concentration of electrolytes than plasma. … Common examples of hypertonic solutions are
D5 in 0.9% normal saline and D5 in lactated ringers
. The administration of hypertonic solutions should be monitored extremely closely, as they can quickly lead to fluid overload.
What will happen when a human RBC is a placed in a hypotonic environment?
Explanation: When RBC is placed in hypotonic solution,
it will start shrinking
. because water present inside the cell will be drawn out into the solution , and the reason behind it is that concentration of RBC is more than the concentration of hypotonic solution.
Are blood cells protected from bursting in a hypotonic solution?
Blood cells are protected from bursting in a hypotonic solution
because of their rigid cell wall
. Cell membranes are freely permeable to water. … The level of the solution in the tube would rise because there are now more dissolved solutes in the tube than the beaker.
When elodea leaves are placed in 10% NaCl What was the result?
Terms in this set (21)
On the Elodea cells the 10% NaCl solution
causes the cell membrane to shrink but the cell wall of plants prevents the entire cell from shrinking
. Because of this the cell appears to have the chloroplasts clustered in the center.
What factors are responsible for the osmotic pressure of a solution?
- Solute concentration is the number of solute particles in a unit volume of the solution that directly determines its potential osmotic pressure.
- Osmotic pressure increases with the increase in temperature.
What is Crenated cell?
In biology, crenation describes
the formation of abnormal notched surfaces on cells as a result of water loss through osmosis
. … The cells start to shrivel and form abnormal spikes and notches on the cell membrane. This process is called crenation.
Why is nucleus not visible in Elodea?
The nucleus is present but not visible, particularly in an Elodea cell,
because the cell membrane is thin, transparent, and in direct contact with the cell wall of the Elodea cell
. Nucleus visibility is difficult since chlorophyll hides other organelles within the cell.
What happens to Elodea cells when salt water is added?
When the Elodea was placed in the salt solution,
the vacuoles disappeared and the protoplasm came away from the cell wall making the organelles appear to be clumped in the middle of the cell
. … Therefore, if it were placed in a hypertonic solution it would lose water and shrivel.
