BIOLOGY: Take large carrot/potato pieces(peeled and unpeeled both) and place in the beakers containing the following liquids. 1. Alcohol 2. Distilled water, 3. Saturated salt solution, 4. Saturated sugar solution, 5. Vinegar and milk. The carrot/potato pieces are observed after 6-8 hours. Answer the following questions by your observations. a. What the difference in the physical state of carrots/potato is as observed in all the six different cases? b. Name the processes involved that has caused a change in carrot / potato
Answers
1.) No observable changes.
2.) The cells of carrot and potato becomes turgid and thus they appear bigger in size.
3.) The cells of the carrot and potato becomes flaccid that is the carrot and potato shrink.
4.) The cells of carrot and potato become flaccid that is they shrink.
5.) No observable change.
6.) No observable change.
EXPLANATION
The experiments are explaining the concept of osmosis and concentration of solutions.
When plant cells are placed in concentrated solutions they become flaccid since water molecules are drawn from the plant cell's cytoplasm to the concentration by osmosis.
When plant cells are placed in distilled water, since distilled water has more solvent molecules and is hypotonoc to the plant cytoplasm, water is drawn into the plant cells by osmosis and thus the cells become turgid.
