Question

explain why cell membrane is semipermeable in nature?​

Answer 1

Cell membrane is semi permeable due to the following reasons:

Explanation:

• The cell membrane acts as a barrier between the outer environment and the interior of a cell.
• If a barrier check is not maintained, then materials will enter inside the cell with out any check.
• This will cause the cell to break.
• Hence, cell membrane is semi permeable so that only limited materials are allowed to enter the cell.

Answer 2

Explanation:

The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids.
