Two fresh potato cylinders of equal length were placed one in distilled water and the other in concentrated sucrose solution:
(a) Account for the change in length of the cylinder in:

(i) Distilled water
(ii) Sucrose solution

(b)
(i) What would be the result in terms of length if a boiled potato was used?
(ii) Explain your answer in(b)(i) Above

(c) State two uses of the physiological process being demonstrated in the experiment

---

(a) (i) Increased in length, absorbed water through osmosis, ( since cylinder cells were hypertonic/ at higher concentration) and become turgid.

(ii) Reduced in length, cylinder host water to the hypertonic sucrose solution/become flaccid.

(b) (i) No change in length

(ii) Cells are dead and cannot carry out osmosis.

(c)
- opening and closing of stomata
- Support in plants
- Movement of water from cell to cell
- Feeding in insectivorous plants
- Absorption of water by root hairs
- Absorption of water in the intestines
- Reabsorption of water in kidney nephron
