Question

Ritika observed onion peel cells in the lab and could view the cell wall, cytoplasm

and nucleus clearly. Suddenly her friend spilled a few drops of salty water on the slide

having onion peel cells.She observes some changes in the cells after sometime

a. What changes would have been observed by Ritika?

b. Name the process that caused the changes in the cells.

c. Would there be similar changes observed ,if she had prepared a slide of cheek cell​

Answer 1

Answer:

Answer 1

As onion peel is a plant cell, so it contains cell wall. As salt water was spilled on the slide and left for some time, Preetha will observe exosmosis in the slide. This will happen because salt water is a hypertonic solution.

Answer 2

It is due to osmosis.

Answer 3

yes the change will be similar because both are prokaryotic cell

(hope it helps you)

Answer 2

Observations are stated below -

a. On the spilling of salty water, cells in the onion peel will shrink. As exosmosis occurs, plasmolysis will be seen.

b. The process of osmosis is responsible for the changes. To be specific, water will move out of the cell and exosmosis will occur.

c. Animal cells have a plasma membrane but do not have a cell wall. So, cells will shrink.
