Penicillin attacks the peptidoglygan cross linking of bacterial cell walls and these bacteria are prokaryote. Human cells do not have cell walls and are eukaryote in domain.
Systemic and target-specific formulations are ways in which herbicides are designed to harm plant -- not human -- cells. But in reality, it is difficult to comprehend and control all of the after- and side-effects of herbicides so environmentalists tend to speak of degrees of ambient residue and of harm to non-target organisms.
It is difficult to develop a chemical that kills fungi but not harm humans because fungi and humans are both eukaryotic organisms, making it challenging to find targets unique to fungi. Additionally, the similarities in cellular structures and processes between fungi and humans also make it hard to find chemicals that selectively target fungal cells over human cells. Furthermore, the potential for off-target effects and toxicity in humans adds complexity to developing such a selective chemical.
Human nerve cells are eukaryotic cells, just like every other human cell.
All cells are smaller than human(except when you're comparing a chicken egg to an embryo)
Antibiotics such as penicillin and tetracycline are effective in killing bacteria by targeting specific bacterial cell components that are absent in human cells, thus reducing the risk of harm to human cells. However, misuse or overuse of antibiotics can lead to antibiotic resistance in bacteria, diminishing their efficacy over time.

Antibiotics work by targeting specific structures or processes in bacteria that are essential for their survival, such as cell wall formation or protein synthesis. These structures or processes are not present in human cells, so the antibiotics are able to selectively kill the bacteria without harming human cells.
When human cells are exposed to seawater, they will likely undergo dehydration due to the higher salt concentration in seawater compared to the inside of the cell. This can lead to cell shrinkage, damage to cell membranes, and ultimately cell death. Additionally, the presence of toxins or contaminants in seawater can further harm human cells.
No. Cells are cells! Cells can't harm you (unless one's a virus.)
Human activities like eating flesh of other animal harm them
it has more human cells actually the human body has more bacterial cells. Although it may seem more likely that the human body would have more human cells than bacterial cells. -Vasillisa
No they dont harm people
