You can't find a nucleus in bacteria you see under a microscope why?

Answer 1

Bacteria are too small for the eye to detect. The lens simply doesn't have a high enough "zoom" to be able to focus on microscopic organisms and objects.

However, there are two bacteria that can be seen with the naked eye:

Epulopiscium fishelsoni

It lives in the guts of surgeonfish, hence the name "fishelsoni." The largest specimen was at around 0,38 mm

Thiomargarita namibiensis

This is the largest known bacteria. It is commonly found in sizes of 0,1 to 0,3 mm, although specimens of up to 0,7 and 0,8 mm have been found.

It lives in the shores of the coastlines around Namibia, which explains why it's called T. Namibiensis.

Answer 2

Bacteria are prokaryotes, meaning they lack a distinct nucleus. Instead, their genetic material is found in a region called the nucleoid, which is not enclosed within a membrane. This lack of a membrane-bound nucleus is a key difference between prokaryotic and eukaryotic cells.

Answer 3

They are prokaryotic cells.
