Question

Quizplus · Accepted Answer

Spores are specialized structures produced by some bacteria that are extremely resistant to boiling and freezing temperatures. Archaeans do not produce these spores. Plasmids are small, circular pieces of DNA that can replicate independently of the bacterial chromosome and can be passed from cell to cell, but they do not confer resistance to extreme temperatures. Ribosomes are essential cellular structures involved in protein synthesis, but they are not resistant to extreme temperatures. Pili are short, hair-like structures that allow bacteria to attach to surfaces or other cells, but they are also not resistant to extreme temperatures.
