Here's why it's important to note that:
* Unlike multicellular organisms (like plants and animals) which are made of many cells working together, bacteria are self-sufficient within their single cell.
* They have a simple cell structure, lacking the complex organelles found in eukaryotic cells.
* They are prokaryotic, meaning they lack a nucleus and other membrane-bound organelles.
So, while bacteria are indeed made of cells, they are single-celled organisms with a distinct and simple cell structure.
