penicillin is an example. It disrupts the pedtidoglycan of the cell membrane in Gram-positive bacteria.

Polymixin antibiotics interact with the lipopolysaccharide molecule of Gram negative bacteria. This component forms the outer leaflet of the outer membrane. Gram-positive bacteria do not have an outer membrane or lipopolysaccharide and thus polymixin antibiotics are unable to bind to the cell.
All bacteria have cell walls. A cell wall outside the cell membrane is found in plants, fungi, bacteria, algae, and archaea. This cell wall is often a target of antibiotics. Viruses also attach to the bacteria cell walls. The bacteria that have cell walls include staph and strep.
Some have outer membrane, some don't. Gram positive bacteria - no outer membrane Gram negative bacteria - with outer membrane
Bacteria can be killed by various methods, including heat, antibiotics, disinfectants, and certain chemicals. Heat can denature the proteins in bacteria, leading to their death. Antibiotics target specific pathways or structures in bacteria, preventing their growth and reproduction. Disinfectants and chemicals can disrupt the cell membrane or interfere with the metabolic processes of bacteria, leading to their elimination.
NO, it surounds the cytoplasm in a cell
Yes, bacteria does indeed have a cell membrane.

In short, it's because they have a membrane around their cell wall that both increases their toxicity, and makes them more resistant to antibiotics. It makes them more resistant because many antibiotics, such as penicillin, work by destroying the cell walls of bacteria. Because they have an extra membrane around their cell walls, gram negative bacteria have extra protection against the antibiotics.
Yes, bacteria does indeed have a cell membrane.
No bacterial cell has a nuclear membrane. A bacteria is defined by not having any membrane-bound organelles.
There are several types of antibiotics that cause damage to the plasma membrane of bacterial cells. These antibiotics injure the the plasma membrane and cause it to die (lysis of the cell). After the membrane has been damaged or destroyed, the bacteria's contents/nurtients escape and the poisons of the antibiotic are allowed to enter the cell and kill it. Antibiotics have selective toxicity so that they can target specific microbes without damaging the person taking the drug.

a cell wall
NO, it surounds the cytoplasm in a cell
The answer is a Cell Wall
