Generally, any damage to the sugar-phosphate "backbone" would be more serious.
However, if the base is altered, rather than merely damaged, it would effectively create a new protein, which could have serious consequences for the cells of an organ. Mutated cells typically fail to perform properly.
It is a tentacle.
the cells would be hard to function and so that cell would be daqmaged

The addition of green color to a phospholipid molecule would not cause any change in the molecule's physical or chemical properties. Phospholipids are structural components of cell membranes with a hydrophilic head and hydrophobic tail, and the addition of a green color would not affect their structure or function.
If the cell membrane was made of a molecule that did not repel water, the membrane would become permeable to water and other water-soluble molecules. This would disrupt the cell's ability to maintain internal conditions necessary for its normal functioning, potentially causing the cell to swell and burst due to osmotic imbalance.
The size and genetic material of the molecule.
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
it would not keep working to do its functions

Globular Proteins
Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.

When a signal molecule activates a transport protein on the cell membrane, it undergoes a conformational change that opens a channel or alters its affinity for the molecule it transports. This allows specific substances to move across the membrane, facilitating cellular communication and maintaining homeostasis.
An allosteric receptor embedded in a cell membrane will change shape in response to the binding of a specific molecule or ligand, which causes a conformational change in the receptor. This change in shape can alter the receptor's ability to interact with other molecules or signaling proteins within the cell, ultimately triggering a cellular response.
