Specialized structures that perform cell functions are organelles.
What are cell organelles?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
An organelle is a particular sort of cell structure. Organelles come in many different varieties. Vesicles are another name for organelles in a cell. They actually serve a purpose that is crucial since all of the processes in a cell must be compartmentalized. Therefore, a membrane is required to surround the processes inside a cell that produce diverse products. Organelles are therefore all membrane-bound in reality. They also distinguish between one function and another. So, for instance, the lysosome breaks down large molecules to make small molecules, while the mitochondrion produces energy by breaking down large molecules.
They must be divided up since the lysosome requires an acidic pH and the mitochondrion relies on all of its pathways, proteins, and enzymes to convert one chemical to another. Additionally, none of the functions would be created if those two substances were combined.

<u>Antibiotics are used to kill bacteria:</u>
Antibiotic is a naturally produced substance that is used to kill bacteria. The first antibiotic was penicillin produced from fungus. The word antibiotic means against life which means it is against the life of pathogenic bacteria.
In the case of the living organism that is treated antibiotic is ‘pro life’. Antimicrobials are used to kill pathogenic microbes like fungus, bacteria, virus etc. Sometimes the microbes become resistant to the antimicrobials and they are said to develop is antimicrobial resistance.
When pathogens develop antimicrobial resistance newer drugs have to be developed in place of the earlier ones to treat the disease.
