Answer 1

Dear Student

1. False, Plant cell kept in hypertonic solution gets plasmolysed due to exosmosis and when placed in hypotonic solution gets turgid due to endosmosis.

2. True

3. False. Diffusion and the osmosis are the same processes in which the molecules move from it's higher concentration to lower concentration.

4. False. The bacterial cells becomes flaccid in presence of salts which prevents the growth of bacteria in pickles.
