LIFE SCIENCE

Detailed explanation-1: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. 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-2: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.

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: -Bacteria are prokaryotes. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid.

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.
