Why plasma membrane is called as selectively permeable membrane ?

Question

Answer

Plasma membrane is known as selectively permeable membrane because it allows entry or exit of only selected substance.....?

Answer

As it allows only some substances to pass through it .?

Answer

Plasma membrane is known as selectively permeable membrane as it allows the entry or exit of some substances in nd out of the cell.

Answer

In actual plasma membrane is selectively permeable..... That's mean is permit water and only some selected solute particles __________
As it is not permeable to all solute particles it nearly act like semipermeable membrane(The membrane which permit only water not solute particles) _________

Answer

It allows the entry of only some selected materials?

Answer

Why Plasma Membrane is called as Selectively Permeable Membrane?
The plasma membrane is called a selectively permeable membrane because it allows certain substances to pass through while restricting the passage of others. This selective permeability is essential for the cell to maintain its internal environment and carry out various functions effectively.

Structure of Plasma Membrane
- The plasma membrane is composed of a double layer of phospholipid molecules with proteins embedded throughout.
- The phospholipid bilayer acts as a barrier to the passage of large or polar molecules, while the proteins help facilitate the movement of specific substances across the membrane.

Function of Selective Permeability
- The selective permeability of the plasma membrane allows essential molecules such as oxygen, carbon dioxide, and water to freely diffuse across the membrane.
- Small non-polar molecules can pass through the lipid bilayer, while larger or polar molecules require specific protein channels or carriers for transport.
- The membrane also plays a crucial role in maintaining the concentration gradients of ions and nutrients inside the cell.

Importance of Selective Permeability
- By regulating the movement of substances in and out of the cell, the plasma membrane helps to prevent the loss of important molecules and maintain the cell's internal environment.
- It also allows the cell to selectively take in nutrients and eliminate waste products, contributing to the overall health and functioning of the cell.
In conclusion, the selective permeability of the plasma membrane is a fundamental characteristic that enables cells to survive and function properly. It ensures that only necessary substances are allowed to enter or exit the cell, contributing to the overall homeostasis and functionality of the cell.

Answer

Because it allows only certain substances inside it?

Answer

As plasma membrane allows only particular elements cross through it.

Answer

Plasma Membrane is semi permeable membrane because it allows or permits the entry and exist of some materials in and out of the cell. It also prevents movements of some other materials therefore it is also called selectively permeable membrane.
