Three in eukaryotes and two in prokaryotes. Think of it this way: suppose you had a string and you cut it in two different places. How many resulting strings would you have? The difference in eukaryotes and prokaryotes is due to the shape of DNA - in eukaryotes, DNA is linear; in prokaryotes, DNA is circular.
Other eukaryotes may eat eukaryotes and some prokaryotes may eat eukaryotes.
Some cells (Eukaryotes in particular) have an organelle known as a cytoskeleton, this organelle governs the shape of a cell and the position of other organelles.
eukaryotes
No, animals are eukaryotes.
No, many eukaryotes are microscopic.
No. They are eukaryotes.
Yes, Mitochondria are specific to eukaryotes.
Eukaryotes, they have a nucleus, while prokaryotes do not.
Humans are classified as eukaryotes.
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
Prokaryotes are older, more basic in function and shape, do not contain a true nucleus or any membrane-bound organelles, unicellular (for the most part - some bacteria have multicellular stages in their life), and consist of bacteria and archae (old bacteria). Eukaryotes can be uni- or multi-cellular, have a nucleus and membrane-bound organelles, are generally more complex in shape and function, much larger than prokaryotes and evolved later in history. These are just some basic comparisons.
