Question

Define prokaryotes and also write the characters which they possess.

Answer 1

prokaroytes are organisms who lack true nucleus. they have their genetic material genome floating in the cytoplasm which is called nucleoid. moreover they do not have well membrane bound cell organelle. they may or may not possess flagella.
eg bacterial cell

Answer 2

Definition of prokaryote: a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacter.

· 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.

An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. The cells of eukaryotes also contain an endoplasmic reticulum and numerous specialized organelles not present in prokaryotes, especially mitochondria, Golgi bodies, and lysosomes.
Characteristics of Eukaryotic Cells - Boundless

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
