Let’s learn about: PROKARYOTIC CELLS.

Remember: There are two types of cells Eukaryotic and Prokaryotic.

Animals and plants have a eukaryotic structure cellular, and both cells have the same structure although the plant cell has a cell wall, vacuole, and chloroplast.

Prokaryotes are the simpler and older of the two major types of cells, they have a cell membrane and one or 

more layers of additional protection from the outside environment. 

Many prokaryotic cells also have
Cilia	Tails	Or other ways in which the cell can control its movement.

Prokaryotes have no nucleolus – the DNA is in the cytoplasm, and it can from small circular strands of DNA called plasmids.

There are two major types of prokaryotes known to scientists today:
Archaebacteria: which are a very old lineage of life with some biochemical differences from bacteria and eukaryotes.	Bacteria: sometimes called “eubacteria,” or “true bacteria” to differentiate them from archaebacteria.

What are the differences between Prokaryotic and Eukaryotic cell?

While eukaryotes are complex, usually multicellular organisms that have eukaryotic cells, prokaryotes are usually single-celled organisms that have simpler prokaryotic cells.

Eukaryotes include all complex life forms including protozoa, plants, fungi, and animals.
 

While prokaryotes are microscopic, mostly single-celled life forms, either archaea or bacteria. 

Prokaryotic cells all have small ribosomes, whereas eukaryotic all have larger ribosomes.
