collect sweet potato, bottle, salt and water. take a bottle full of water and add salt then put the sweet potato inside the bottle observe for few days.what happens? note your observations. how can you prove that sweet potato is also a living thing?
Answers
Explanation:
When we add salt to the water the water solution becomes concentrated with salt.
When we put the sweet potato the solution becomes hypertonic to the cells of the sweet potato.
Since the sweet potato cells are hypotonic to the salt solution water from the sweet potato cells will be drawn to the salt solution by osmosis.
This happens until the salt solution is isotonic to the sweet potato cells.
Since water has been drawn from the sweet potato cells, the cells become plasmolysed and the sweet potato becomes flaccid.
To prove that the sweet potato cell is living we should observe that the sweet potato becomes flaccid.
Flaccid - This is when the plant has lost its turgor pressure and in the case of a sweet potato it becomes soft.
Hypotonic - when the solvent molecules are more in a solution than solute molecules.
Hypertonic solution - when solute molecules are more in a solution than solvent molecules.
Isotonic solution - when there is equal concentration of solute and solvent molecules.
