On adding salt, Vegetables release water due to exosmosis. Exosmosis occurs whenever the external medium is hypertonic as compared to the osmotic concentration inside living cells.

Digested food is taken in the intestinal cells by the following process: (i) Glucose, amino acids and some ions - Active transport. (ll) Fatty acids, glycerol - Diffusion (Passive transport) (iii) Water - Osmosis.

Concentrated salt solution is a hypertonic solution so causes irritation and excessive dehydration in the wall of alimentary canal dr.ie to exosmosis. There is uncomfortable stretching which causes reverse movements and hence vomiting.

Bacteria do not have chloroplasts but some bacteria are photoautotrophic in nature and perform photosynthesis. Which part of bacterial cell perform this?
Photoautotrophic bacteria posses photosvnthetic pigments inside small vesicles which may be attached to the plasma membrane.

A person takes concentrated solution of salt. After some time he starts vomiting. What is the phenomenon responsible for such a situation? Explain
Concentrated salt solution is a hypertonic solution so causes irritation and excessive dehydration in the wall of alimentary canal dr.ie to exosmosis. There is uncomfortable stretching which causes reverse movements and hence vomiting.
