Cells are the basic unit of structure and function of all living beings.Discovered by Rober Hooke in 1665.

THE CELL THEORY TELLS US THAT:
-All living beings are made up of cells.-The cell is the basic unit of structure and functon.-Every cell arrives from a previuosly one.

There are two types of cells EUKARYOTIC cells and PROKARYOTIC cells.EUKARYOTIC cells are those that have a nucleus and they are wider than prokaryotic ones, eukaryotic cells contain membrane-bound compartments in which specific metabolic activities take place. They have the DNA on the nucleus. Examples of eukaryotic cells are: Plants, animals, fungi, slime moulds, protozoa and algae cells. But we are going to talk only but the two most important that are the Animal and the Plant cell.

PROKARYOTIC cell are those without any nucleus on them they are simple and smaller than a eukaryote cell.There are two kinds of prokaryotes: bacteria and archaea; these share a similar structure.
Bacteria
Archaea
