GENERAL HISTOLOGY

Detailed explanation-1: -Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. Among prokaryotes, bacteria are the most common and multiply very fast. They are single-celled and range in size from 0.2 to 10 microns (about 10 times smaller than most plant and animal cells).

Detailed explanation-2: -Bacteria are classified as prokaryotes, along with another group of single-celled organisms, the archaea. Prokaryotes are tiny, but in a very real sense, they dominate the Earth.

Detailed explanation-3: -Bacteria are examples of the prokaryotic cell type. An example is E. coli. In general, prokaryotic cells are those that do not have a membrane-bound nucleus.

Detailed explanation-4: -Examples of prokaryotic cells are cyanobacteria, E. coli, mycoplasma, etc. ‘Pro’ means ‘before’ and ‘karyon’ means ‘nucleus’. Prokaryotic cells also lack membrane-bound cell organelles.

Detailed explanation-5: -Bacteria are classified as prokaryotes because they lack a nucleus and membrane-bound organelles. All bacteria are prokaryotes, and while they may have other cellular structures such as a cell wall, cilia, or flagella, they lack a nucleus, making them prokaryotic.
