NEET BIOLOGY

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 lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.

Detailed explanation-3: -Eukaryotic cells have a nucleus, a membrane-bound chamber where DNA is stored, while prokaryotic cells don’t. This is the feature that formally separates the two groups. Eukaryotes usually have other membrane-bound organelles in addition to the nucleus, while prokaryotes don’t.

Detailed explanation-4: -Prokaryotes lack all membrane-bound organelles, including nuclei, mitochondria, endoplasmic reticulum, chloroplasts, and lysosomes.

Detailed explanation-5: -Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
