Answer 1

Answer:

1. Isotonic

2. Hypotonic

3. hypertonic

4. hypotonic

5. Hypertonic

6. Hypotonic

Explanation:

Tonicity refers to the amount of the solute concentration dissolved in the solution which determines the direction of the diffusion across the semipermeable membrane.

There are three types of tonic solutions formed on the basis of solute concentration which are:

1. Isotonic solution: When the solute concentration is the same across both the sides of the semipermeable membrane. When a cell is placed in isotonic solution it remains in the same state as no movement of water is observed as in option 1.

2. Hypertonic solution: The solution which contains a high amount of solute and a low amount of water. When the cell is placed in this solution the cell shrivels as the water movement is observed from the cell to outside down the concentration gradient like in option-3 and 5.

3. Hypotonic solution: The solution which contains the low amount of solute and high amount of water, when a cell is kept in the hypotonic solution the cell swell and could become flaccid if is a plant cell as in option 2, 4 and 6.
