Most cells consist of one nucleus, the brain of the cell.
cytoplasm, the fluid that fills the cell
and various organelles, like the organs in your body.
All surrounded by a semipermeable cell membrane
Well, that's the short version.
Start thinking as the cell now as a little body
that is analogous to your own body.
The structure of cells has evolved over billions of years
beginning with the first cell which emerged from the primodial ooze
There are two types of cells
The difference between the two is simple:
perhaps you've heard of bacteria.
Basically, bacteria are the most common procaryotic cells.
They don't even have nuclei or organelles,
but, of course, they do have DNA, which we'll get to later.
Eukaryotes, on the other hand, do have nuclei and organelles
and are enclosed by a membrane
Eukaryotes is what you picture as the typical cell
