What similarities and difference does a Eukaryote cell have with a plant or animal cell in structure?

What structures existed in a Eukaryote cell?

Are any of these structures present in modern plant and animal cells?

Has genetic material of an Eukaryote been sequenced?

Almost all plants and animals and fungi (i.e., almost all largish organism on the planet) have eukaryotic cells. Eukaryotes really look kind of like two cells in one: there's the main big cell and then there's the nucleus, which seems like it might have been another different kind of cell that the larger cell enveloped a bajillion years ago. Fascinating theory!

And, yes, when you talk about sequencing the genome of a plant or animal or fungi, you are talking about sequencing the nuclear DNA of a eukaryote.

Asker's rating:

Will you list each common structure?

1. Both have DNA strands
2. Both have a celluar membrane
3. What high level structures do both cells create?

Yea, both have DNA (there maybe protists that only have RNA, not sure) and both have membranes (which is pretty much the definition of a cell: there's an inside and an outside). As far as "high level structures" well, I think prokaryotes are almost entirely unicellular (e.g., bacteria) and so never create any structures at all. I can't think of any, anyhow.

Lets see how much I remember from the biology class I took summer before last. I loved the class, but this is one of the few opportunities I've had to apply the knowledge. There are many components besides the nucleus. Most are common to plant and animals, a few are unique to animals.

The organelles are mitochondria, smooth er, rough er, the plasma membrane. The mitochondria makes sugar, ATP.

The amino acids in DNA are CTAG. I remember the DNA replication being like a zipper splitting the helix of two strands and then hyrdorgen bonds bringing them back together. The ordering of the CTAG determines the viability of the new strand.

I loved learning the whole process of meiosis and mitosis. Seeing it under the microscope was very cool.

If it hadn't been for that darned frog dissection, I might have pursued more classes in biology.
