NEET BIOLOGY

Detailed explanation-1: -Prokaryotes are unicellular organisms that lack membrane-bound structures, the most noteworthy of which is the nucleus. Prokaryotic cells tend to be small, simple cells, measuring around 0.1-5 m in diameter. The key structures present in a prokaryote cell.

Detailed explanation-2: -The cell types in Bacteria and Archaea are considered as “prokaryotes.” The use of the term prokaryote was first introduced as a result of electron microscope studies showing a shared simple cell structure among bacteria (Stanier & Van Niel 1962).

Detailed explanation-3: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.

Detailed explanation-4: -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-5: -Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
