If a parent bacterial cell is able to survive in the presence of the antibiotic penicillin, subsequent generations from this parent will be resistant to penicillin.
This resistance can occur through several mechanisms, such as acquiring mutations in their genetic material or through horizontal gene transfer from other bacteria that carry antibiotic resistance genes. As a result, the offspring will inherit the traits that allow them to survive in the presence of penicillin, leading to a population of bacteria that are resistant to the antibiotic.
