Human cells are eukaryotic and bacteria cells are prokaryotic. Humans have their DNA inside the nucleus, whereas bacteria have it contained within a plasmid. Human cells have larger ribosomes than bacterial cells, also human cells are a lot bigger than bacterial cells. Human cells have mitochondria while bacterial cells do not. I'm unsure about this one but I think human cells have membrane bound organelles whereas bacterial cells do not. Also human cells do not have a capsule or a flagella (apart from sperm, which do have a flagella), bacterial cells can have these two things but not all of them do.
I've probably missed something out but I can't remember it.

I am making all this up, so double-check it!
1. Bacteria often have a cell wall or capsule or both. Human cells don't have that.
2. Bacteria are "prokaryotic" and human cells are "eukaryotic." This means that a bacterium does not have a nucleus, but a human cell does.
3. In human cells, the main genome is stored on several linear strands of DNA known as chromatin (or chromosomes). The main genome is kept within the cell nucleus.
In bacteria, the main genome may be stored on a circular strand of DNA, and is not within a separate nuclear structure. It may be bound at one point to the cell's membrane.
4. Human cells have complex organelles including mitochondria. Bacteria don't.
5. Human cells may import or export substances using "bubble" structures called vesicles. Bacteria don't -- bacteria generally secrete their juices directly to the "outside."
6. Human cells (5 um) are quite a bit bigger than bacteria (1um).
7. Human cells have membranous and microtubule internal structures. Bacteria generally don't.

Human cells are eukaryotic (having a nucleus) while bacterial cells are prokaryotic (having no nucleus). Also, human DNA is double-stranded and in the form of a double helix, bacterial DNA is often called a plasmid, shaped like a circle. In a nutshell, human cells are more complex than bacterial cells.

human cells have a far different structure than bacterial cells. bacterialcells have a far simpler DNA structure housed in a different container than a nucleus. the cells of a human and indeed all animals have an extra layer than bacterial cells, and human cells are more contained and controlled than bacterial cells.

Dammit! Thought I'd escaped all this with the whole exam thing! O.k bacteria have flagellum, human cells don't. Bacteria have no nucleus hence -prokaryotic cell ('before nucleus' is a literal translation) Bacteria have plasmids, human cells don't. Human cells have a golgi body, rough and smooth endoplasmic reticulum and mitochondria, bacteria cells don't.
Now why am I doing your homework?

Human cells are eukaryotes or the cells have a nucleus. Bactiarial cells are prokaryotic having no nucleus.

human cell is eukariotic cell which contain nucleus , membrane bound organeles, where as bactera is prokariote not having nucleus & membrane bound organeles,
bacterial cell wall is made from peptidoglycon , where as human cell dose not have cell wall,

Go on then, make it 20 points in total!
I'll even have a crack at the answer, one are in humans and one are in bacteria!!!!!!!!!!!!!!!!!!!!!!!!
