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 (meaning ‘before nucleus’) are cells without a definite nucleus. The DNA floats in the cytoplasm and they divide through mitosis. RBC and platelets present in eukaryotes also do not have the nucleus.

Detailed explanation-3: -Bacteria. Bacteria are microorganisms made up of a single prokaryotic cell. There are two general categories of cells: prokaryotic and eukaryotic. Sometimes, organisms are referred to as prokaryotes or eukaryotes, based on the type of cell(s) that compose them.

Detailed explanation-4: -Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Detailed explanation-5: -prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes.
