Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Prokaryotic cells include bacteria.
A
True
B
False
Explanation: 

Detailed explanation-1: -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-2: -Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-3: -All cells fall into one of these two broad categories. Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes-pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes-eu means true-and are made up of eukaryotic cells.

Detailed explanation-4: -Prokaryotic cells do not have a true nucleus that contains their genetic material as eukaryotic cells do. Instead, prokaryotic cells have a nucleoid region, which is an irregularly-shaped region that contains the cell’s DNA and is not surrounded by a nuclear envelope.

Detailed explanation-5: -Bacterial cells are prokaryotic. They possess a ‘nucleoid’, an irregular-shaped region of the cell that contains circular DNA. Moreover, membrane-bound cell organelles are also absent in them.
