THE CELL: 

THE CELL The cell is the smallest unit that shows the properties of life (metabolism, homeostasis, growth, reproduction). The study of structure and peculiarities of lifestyle of micro organisms is called microbiology.

THE CELL THEORY by Theodor Schwann and Matthias Schleiden (published 1839): 

THE CELL THEORY by Theodor Schwann and Matthias Schleiden (published 1839) Every living organism consists of one or more cells A cell is the smallest unit of life, individually alive even as part of a multi-celled organism. All living cells come from division of others, pre-existing cells. Cells contain hereditary material which they pass to their offspring during the division. Everyone consists of cells. Cells are alive. Cells reproduce. Cells have DNA.

No nucleus PROKARYOTES vs. EUKARYOTES

PROKARYOTES (“BEFORE THE NUCLEUS”): 

PROKARYOTES (“BEFORE THE NUCLEUS”) Bacteria, nitrogen-fixing cyanobacteria and archaebacteria (Archaea) comprise all prokaryotes.

Prokaryotic cell Characteristics 1) No nucleus. The chromosome is in the nucleoid. 2) Only one chromosome (a DNA molecule=. Many species obtain plasmids. 3) Ribosomes are distributed in the cytoplasm. :
