Figures inventor of the cell theory:

Robert Hooke (1635-1703)

The first person to mention the term, namely cellular cell (small room that was empty and observed slice the cork (Quercus Suber), is a dead cell which does not have the contents of the cells).

Antonie van Leeuwenhoek (1723)

An expert from the Netherlands sharpening lens, making simple microscopes, Checking fluid microscopic drop of water in the pond "animalcules" (small animal) is a bacterial cell and the person who first described the bacterial forms.

Robert Brown (1833)

Scottish scientist who first discovered the cell nucleus of the incision orchid cell nucleus nukleus.Nukleus describes as a very important cell structures like life.

Felix Durjadin (1835)

Prominent French nationals who first discovered the living cell fluid (sarkode) which is an important part of the cell Menururutnya most important part of the cell is the cell contents in the form of liquid life are within a lumen.

Johannes Purkinje

THAT is a scientist stating the contents of cells is protoplasm. Protoplasm is an important material in cells that sustain life.

The structure of prokaryotic cells (cut no nuclear membrane):

Has the plasma membrane, nucleoid (such as DNA and RNA), and the cytoplasm contains ribosomes.

Not having endomembrane (membrane in the cell nucleus), does not have mitochondria and chloroplasts, but has the same functional structure that is mesosom and chromatophore. Example: bacteria and algae blue.

The parts of the prokaryotic cells (Escherichia coli):

a. Cell wall

Composed of cell wall polysaccharides, fats, and proteins.
function:

as a protector;
giver fixed form;
There are pores as the entry and exit of molecules.

b. The plasma membrane

Composed of plasma membrane molecules of fat and protein.
Function:

as a protective molecular cell to the surrounding environment;
regulate the traffic of molecules and
ions out of and into the body.

c. cytoplasm

Cytoplasm Composed of water, protein, fat, minerals, and enzymes.
Function:

Enzymes, use to digest food extracellular and cell metabolism.

d. Mesosom

There Mesosom on a curved plasma membrane into the cell organelles mesosom form.
Function:

As an energy producer;
There is a respiratory enzymes involved in the oxidation reaction to produce energy.

f. DNA (deoxyribonucleic acid)

DNA (Deoksironukleat acid) is a compound on deoxyribose sugar, phosphate and nitrogen bases.
function:

As a carrier of genetic information than the properties that will be inherited by the offspring.

g. RNA (Ribonucleic Acid)

RNA (Ribonucleic Acid) is the result of transcription (print and copy) of DNA.
function:

Bringing the genetic code in accordance with the order of DNA.
