Cells and organelles 

 Eukaryotic cells are complex where as prokaryotic cells are not.   

Eukaryotic:

- Larger cells

- DNA is linear

- Nucleus present

- No cell wall, cellulose, cell wall or chitin cell wall

- Many organelles, mitochondria present 

-Large ribosomes

Prokaryotes:

- Very small cells

- DNA circular

- No nucleaus

- Cell wall made of polysaccharide

-Few organelles, no mitochondria

-Small ribosomes 

A good way of telling the two types of cells apart, is that eukaryotic cells have nucleaus and they have more organelles.

  Organelles are parts of cells.

Here are list of organelles and their function:
