From what i know common features to eukaryotic cells are:
1: Plasma membrane
2: Cytoskeleton
3: Nuclear envelope (that is the double membraned nucleus)
4: Membrane bound organelles
5: Endoplasmic Reticulum
6: Ribosomes
7: Mitocondrion
You may know that cillia, flagella, and centrioles are present in animals cells and not in plant cells, however this is not completely accurate. From what i know these are also present in the cells of seedless plants such as moses and ferns.

Hope it helps,
Sinead

I don't know if they are present in moses and ferns but the Euglena virdis and other members of the protista kngdom posses these structures(from here both plants and animals were "born")

Vacuoles are also in eukaryotic cells... don't assume that people know what "Membrane bound organelles" are... Tina Hakola - They are organelles that are bound by a membrane - Mitocondrion, vacuoles, chloroplasts (plants only), and the nucleus. Lysosomes are also only in eukaryotic cells :D

Eh...just note that plant cells don't have centrioles in their microtubule organizing center so eukarytoe cells dont all have that in common...some cells, like erythrocytes, have no nuclei so it really all depends what types of eukaryotic cells you're talking about. in general, most eukaryotic cells have plastids or mitochondria, a nucleus, golgi apparatus and other well known cellular organelles.

Every living cell needs genetic material, in our case, a nucleus. erythrocytes have a nucleus at all organisms except mamals. Why do you think at mamals the erythrocytes only live for 30 days or so? No living thing can survive for long without genetic material(and don't give me the prions 8) 8) -they are not living things :D :D )

yeah youre right, but erythryocytes ARE eukaryotic so they count as being super-specialized eukaryotic cells. biology is seriously full of all those things that cheat the "rules." lol
