      i don’t understand the difference between prokaryotic cells and eukaryotic cells

      Prokaryotic cells were the first cells. They are much smaller, and are only found in the Kingdom Monera. They have no organelles, no nucleus, and their DNA is circular.

      Eukaryotic cells came later. They are gigantic compared to the Prokaryotic cell. They are found the rest of the kingdoms (Anamalia, Plantae, Fungi, and Protista). They have organelles, a nucleus, and their DNA is linear.

      Prokaryotic cells only have a cell membrane, DNA, ribosomes, and cytoplasm. eukaryotic cells are compartmentalized and have other organelles and their DNA is all stored in a central “command center” for the cell; the nucleus.

      Does that help?

      They had a cell membrane, ribosomes, and cytoplasm… those are organelles.

      I think this explanation is more clear:
      They have no membrane bound organelles.

      a simple way to tell the difference is that prokaryotic cells are single celled and eucaryotic means that it’s mult icelled

      That’s wrong. Eukaryotic only means has a nucleus.

      Most multicellular organisms are made up of eukaryotic cells…. Most Prokaryotic organisms are really small or are only one cell organisms.

      yes, THANKS, that helped a lot.
      but i’m still a little bit confuse about the part about “prokaryotic cells are single celled and eucaryotic means that it’s mult icelled”. is that right or wrong?

      Semi-correct. All prokaryotic cells are unicellular organisms. Eukaryotic cells can either be unicelluler (Ameba), or multicellular (Humans).

      P.S. Yes, I DID spell Ameba right…”Ameoba” is the British way of spelling it 😉

      In my bio book it is spelled “Amoeba” so i guess it is correct anyway…

      The Eukaryotic are highly structured and are larger then the cell of bacteria. They have also developed a specialized packaging and transport mechanisms that may be necessary to support their larger size. These also have specialized compartments (membrane-bound organelles). The prefix eu-means true.

      The Prokaryotic is simple in structure, with no recognizable organelles. They have an outer cell wall that gives them shape. Just under the rigid cell wall is the more fluid cell membrane. The cytoplasm enclosed within the cell membrane does not exhibit much structure when viewed by electron microscopy. These lack membrane-bound organelles. Prokaryotic means before having nucleus.

      Just to help you understand the terms eukaryotes and prokaryotes better:
      The word karyon itself means nucleus. The word eukaryotes means “true nucleus” and the word prokaryotes means “before (pro) and nucleus (karyon)”.

      The basic difference between eukaryotes and prokaryotes is that the genetic material of eukaryotes is enclosed in a nucleus whereas the genetic material of prokaryotes is simply suspended into the cytoplasm. There are also other features that distinguish prokaryotes from eukaryotes as outlined in the previous posts above.

      Are you daft it’s English not British! It’s like me saying that it’s the americas way of saying it!

      Life is immeasurable.. that’s being BIO.
      Cells are really incredibly, so SIGNIFICANT.
      How life is so diversed… two footing points, from prokaryotic and eukaryotic functional units!

      We call our members in our organization, "KA-BIO" sounds like "KABAYO" which means "horse". "KA-BIO" means, my fellow BIO member.
      When non-bio people here that, they laugh since they think of the horse "thing". Only KA-BIOs knows what it mean!
