What would happen if the plasma membrane ruptures or breaks down class 9 Ncert?

What would happen if the plasma membrane ruptures or breaks down class 9 Ncert?

Answer- If ever the plasma membrane ruptures or breakdown then the cell will not be able to exchange material from its surroundings by diffusion. As a result of it the protoplasmic material will disappear and the cell will die.

What would happen if the plasma membrane ruptures or breakdown any three points?

If the plasma membrane ruptures or breaks down, the cell will not be able to exchange material from its surroundings by diffusion or osmosis because it acts as a mechanical barrier. Thereafter, the protoplasmic material will be disappeared, and the cell will die.

What happens when the cell membrane is damaged?

Plasma membrane damage results in loss of osmotic balance and influx of fluids and ions, as well as loss of proteins, enzymes, coenzymes, and ribonucleic acids. The cells may also leak metabolites, which are vital for the reconstitution of ATP, thus further depleting net intracellular high-energy phosphates.

What would happen if the plasma membrane refuse or breakdown?

Therefore, it is called a selectively permeable membrane. If plasma membrane is ruptured or broken down, all useful substances will move out of the cell and there will be no difference between cell content and its external environment. Ultimately, the cell will lose its normal shape and would die.

What would happen if there was no phospholipid bilayer?

If phospholipid bilayer diffusion is normally negligible, there will be tissues (largely lacking in transporters that may be expressed elsewhere) which, despite the relative functional similarity of their phospholipids, are very poor at taking up drugs: the blood–brain [33], blood–testis [34], and blood–retina [35] …

Why is plasma membrane called?

The cell contains a protoplasm (or simply plasm), which is the semi-fluid living matter. This living matter or plasm is contained inside a biological membrane referred to as the plasma membrane. Because it surrounds the entire cell, this plasma membrane is specifically referred to as the cell membrane.

How is damage to the cell membrane likely to impact the functions of the cell?

Explanation: damage to the cell membranes can lead to entry of toxic substance inside the cell which can destroy the nucleus and other cell organelles. Damage to cell membrane can also lead to leakage of important cell constituents required for various metabolism of the cell.

What is plasma membrane function?

The function of the plasma membrane The main function of the plasma membrane is to separate and protect the intracellular environment from the extracellular space. The plasma membrane is semi-permeable and selectively regulates the passage and transport of various molecules and compounds in and out of the cell.

What affects plasma membrane?

There are 3 main factors that influence cell membrane fluidity: Temperature: The temperature will affect how the phospholipids move and how close together they are found. When it’s cold they are found closer together and when it’s hot they move farther apart.

What would happen to the life of the cell if a the plasma membrane ruptures or breaks down B if there was no Golgi apparatus?

In the absence of the Golgi apparatus, lysosomes would not be produced, and the accumulation of dead and damaged organelles and molecules in the cell would ultimately result in cell death.

What are three functions of the plasma membrane?

Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the …

Why plasma membrane must be a bilayer?

The plasma membrane, which is called the selectively permeable membrane of the cell must be a bilayer because: It facilitates communication and signalling between the cells. It acts as a selective barrier between the external and interior of the cell.
