Question

the semi fluid nature of the membrane-
helps in quick repair
provides dynamic nature
gives semi permeable nature
both 2 and 3
all 1,2 and 3

pls explain the correct answer

Answer 1

Answer:all 1,2 and 3

Explanation:The fluid nature of lipids enables lateral movement of proteins within the overall bilayer. As we know proteins are needed for repair(option 1)

As we know 'dynamic' means to be active. That is the fluidity of the biomembrane helps in transport of materials by the process of passive transport and active transport(option2)

We already know that the plasma membrane ( or biomembrane) is selectively permeable due to the presence of proteins.(option3)

I hope this helped....

Answer 2

The correct answer for the given question is d. All 1, 2, and 3.

Here is the explanation-

• The cell membrane, which is also known as the plasma membrane forms the outer cell covering. The membrane is made up of a bilayer of phospholipids along with proteins that are embedded in the structure.
  
• The semi-fluid nature of the plasma membrane helps in the repair of the cell as the membrane is responsible for the growth of the cell, and cell division.
  
• The membrane also works in maintaining the dynamic structure of the cell.
  
• The semipermeable membrane allows selective absorption of nutrients between the cell and the surroundings. This semi-permeable membrane helps assist the entry and exit of proteins or other substances across the cell.

Hence, the correct answer will include all three points given in the option, which means d. All 1, 2, and 3.
