Question

When a red blood cell is placed in a hypotonic environment, the cell will:

a. crenate

b. shrivel up

c. swell and burst

d. plasmolyse

Answer 1

I think it is b.

Answer 2

Hypotonic means less concentration than Cell

Answer 3

Got it ?

Answer 4

So, is the answer d?

Answer 5

Shrivel up means to "wrinkle and contract or cause to wrinkle and contract, especially due to loss of moisture."
Shrink and shrivel are same things

Answer 6

So, what is plasmolyse? Can you explain?

Answer 7

Wait !

Answer 8

Since the solute solution is less outside, water (solvent) will move into the RBC and will cause it to swell up

Answer 9

getting my points ?

Answer 10

Shriveling and plasmolysis are same things. The only difference is that plasmolysis term is used with plant cell.

Answer 11

Plasmolysis is the term which describes plant cells when the cytoplasm shrinks from the cell wall in a hypertonic environment. In plasmolysis, the cell wall stays intact, but the plasma membrane shrinks and the chloroplasts of the plant cell concentrate in the center of the cell.

Answer 12

When I searched on google, it defined it as "Plasmolysis is the process in plant cells where the cytoplasm pulls away from the cell wall due to the loss of water through osmosis." It also says that it occurs in a hypertonic solution.

Answer 13

yes plasmolysis and shrivelling up or shrinking all are same things. Plasmolysis is exclusively used with plant cells. The protoplast contracts but the rigid cell wall remains as it in hypertonic solution.

Answer 14

In this question RBC is kept under hypotonic solution so the reverse process will occur and the cell willl swell up and finally will burst

Answer 15

Oh, so Plasmolysis happens in plant cells, and in red blood cells, the reverse will happen?

Answer 16

In RBC
Hypertonic-----> Shrivel/Shrink
Hypotonic-----> Swell and Burst
Isotonic------> Nothing

In plant cell
Hypertonic-----> Plasmolysis.
Hypotonic-----> Swell and Burst
Isotonic------> Nothing

Answer 17

Okay, I understand now. Thanks!
