Detailed explanation-1: -Bacteria are single-cell organisms. Some bacteria need oxygen to survive and others do not. Some love the heat, while others prefer a cold environment. Well-known examples of bacteria include salmonella and staphylococcus bacteria.

Detailed explanation-2: -Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet’s ecosystems.

Detailed explanation-3: -All bacteria are unicellular, and all are prokaryotic. Prokaryotes are organisms that are made of one prokaryotic cell, which is a cell type that lacks membrane-bound organelles and has no true nucleus.

Detailed explanation-4: -Bacteria are tiny, single-celled organisms that get nutrients from their environments. Some bacteria are good for our bodies-they help keep the digestive system in working order and keep harmful bacteria from moving in. Some bacteria are used to make medicines and vaccines.

Detailed explanation-5: -No, bacteria are prokaryotic organisms, meaning that they are all single-celled. However, they do have tendencies to form colonies. So, while they do live in groups, they are all completely independent organisms. Only eukaryotic organisms can be multi-cellular.
