Question

do bacteria cells have nucleus​

Answer 1

Answer:

No, Bacteria doesn't have nucleus

$\huge\bold{Explanation:-}$

➡️It is so because they are prokaryotes

PROKARYOTES:-

➡️It is present in unicellular organisms

➡️It lacks nucleus, mitochondria, or any other membrane-bound organelle

➡️The word prokaryotic means "primitive" in Greek Language

➡️For eg:- Bacteria

NUCLEUS:-

⏩It is a dense structure located in the centre of the animal cell and towards the cell membrane in the plant cell is called nucleus

⏩It is spherical in animal cell but becomes oval in plant cell because exerted by vacuole against the cell membrane

⏩ Normally, a single nucleus is present in most of the cells but some cells like Paramecium contains 2 cells

⏩Some cells lacks nucleus at maturity

⏩Eg:- RBC cells in mammals

NUCLEAR MEMBRANE:-

⏩ Nucleus is covered by a double membrane which separates Nucleus from the cytoplasm

⏩It's not continuous and is characterised by pressure of a number of openings called Nuclear pores

⏩These pores allow in the exchange of the material between the Nucleus and the cytoplasm

Answer 2

Answer:

Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.
