Question

Select the odd one out: (a)The movement of water across a semi permeable membrane is affected by the amount of substances dissolved in it. (b)Membranes are made of organic molecules like proteins and lipids (c)Molecules soluble in organic solvents can easily pass through the membrane. (d)Plasma membranes contain chitin sugar in plants

Answer 1

Answer:

The correct is 'Plasma membrane contain chitin sugar in plants'.

Explanation:

-The movement of water across a semi-permeable membrane is affected by the amount of substance dissolved in it. As water moves from higher concentration to lower concentration.

-Membranes are made of organic molecules like proteins and lipids. The ratio of protein and lipids vary considerably in different cell types. In human beings, the membrane of the erythrocyte has approximately 52 per cent protein and 40 per cent lipids.

-Molecules soluble in organic solvents can easily pass through the membrane as the membrane is lipophilic.

-Cell walls of fungi contain chitin sugar.

So, the correct answer is 'Plasma membrane contain chitin sugar in plants'
