Question

Osmosis is a process by which molecules of a solvent tend to pass
through a semi permeable membrane from a less concentrated solution
into a more concentrated one. Can you pick out the option among the
following which does not belong to this process?
(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 such as 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:

d

Explanation:

this is your answer        

Answer 2

Plasma membranes contain chitin sugar in plants. This is the option that does not belong to the process of osmosis. (Option d)

• A plasma membrane is a membrane that is only selectively permeable.
• It is a living membrane that is extremely thin and elastic.
• This membrane is lipophilic which means it can dissolve as well as combine with lipids and fats, therefore it allows the passage of molecules that are soluble in organic solvents.
• Its chemical composition majorly comprises lipids and proteins.
• It also contains a very small amount of water and carbohydrates.
• Hence, the plasma membrane of plants does not contain chitin.
