Question

How do prokaryotic cells and eukaryotic cells differ?

Answer 1

Hint: All types of life, from minute bacteria to towering giant Sequoias, are biotic elements of the world. At the microscopic level, however all living organisms are composed of the same basic unit, the cell.

Complete answer:

	Prokaryotic cell	Eukaryotic cell
Type of cell	Always unicellular	Unicellular and Multicellular
Cell Size	Ranges in diameter from 0.2 μm-2.0 μm in size	The scale varies in diameter from 10 μm to 100 μm
Cell wall	Present with chemically complex in nature	When present chemically simple in nature
Nucleus	Absent.Instead they have nucleoid region in the cell	Present
Ribosomes	Smaller in size and spherical in shape	Larger comparatively and linear in shape
DNA arrangement	Circular	Linear
Mitochondria	Absent	Present
Cytoplasm	Present but cell organelles are absent	Both cytoplasm and cell organelles are present
Endoplasmic reticulum	Absent	Present
Plasmids	Present	Very rarely found in eukaryotes
Lysosome	Both lysosome and centrosome are absent	Both lysosome and centrosome are present
Cell division	Binary fission occurs	Cell is divided through mitosis
Flagella	Present and smaller in size	Present and larger in size
Reproduction	Asexual reproduction	Both asexual and sexual reproduction
Transcription	It occurs in cytoplasm	It occurs inside nucleus
Golgi apparatus	Absent	Present
Cytoskeleton	Absent	Present
Pili and Fimbriae	May have both pili and fimbriae	Absent
Chloroplast	Absent and chlorophyll is scattered in the cytoplasm	Present in plant cells
Vacuoles	Absent	Present
Chromosome	Only one chromosome is present	More than one chromosome are present
Example	Bacteria	Plant and animal cell

Note: Eventual developments in science and technology, with new studies and observations about its structure and cellular elements, shed further light on the cell. The idea of prokaryotic cells and eukaryotic cells was postulated by scientists during the 1950s, with earlier groundwork laid in 1925 by Edouard Chatton, a French biologist.
