The cell would be unable to maintain a stable internal environment.
If the cell membrane were completely made of polar substances, it would be impermeable to non-polar molecules like oxygen and carbon dioxide, affecting the cell's ability to exchange gases with its environment. This could disrupt important cellular processes like respiration, leading to energy depletion and potential cell death.
The cell would be unable to maintain a stable internal environment.
A polar substance can cross a cell's plasma membrane through facilitated diffusion, which does not require energy expenditure. In this process, specific transport proteins help the polar substance move down its concentration gradient from an area of higher concentration to an area of lower concentration. This movement occurs until equilibrium is reached.
Large polar molecules like glucose and ions such as sodium and potassium are not permeable through the cell membrane. These molecules require specific transport proteins or channels to facilitate their movement across the membrane.
If the fatty acids in a cell membrane were polar molecules, the overall structure of the membrane would be compromised. Polar fatty acids would lead to increased interactions with water, disrupting the bilayer arrangement essential for membrane integrity. This change could hinder the membrane's ability to act as a barrier, impairing cellular function and potentially leading to cell lysis or dysfunction. Additionally, the membrane's fluidity and permeability properties would be altered, affecting the transport of molecules across the membrane.

a substance such as sugar
A substance that ionises completely in water which in most cases is an acid are known as strong acids,they can also be called polar substances.
The cell would dissolve in water.
The cell would dissolve in water.
It would dissolve in water or in polar liquids and would not be recognisable as a cell.

When a substance is called polar, it means water-loving. Chlorophyll is not a polar substance. However, Chlorophyll B is a polar substance.
