What is the definition of prokaryote & eukaryote?

Can you please put it in short words and make it easy to read? I’m not good with handling big vocab. thank you.

  • prokaryote: an organism that doesn’t have a nucleus (like bacteria) It still has DNA of course, but not enclosed in a neat little sack

    Eukaryote: an organism that does have a nucleus (like me and you)

    A couple of corrections to the other answers:

    Bacteria are NOT the only prokaryotes. Archea are also prokaryotes.

    Not all prokaryotes are strictly single celled. Many, perhaps most even, form larger structures with differentiated function.

  • Prokaryote Definition

  • Prokaryote:

    Prokaryotes, which have NO defined nucleus or membrance- bound organelles.

    Eukaryote:

    Eukaryote, which have a TRUE nucleus and a complex structure including many membrance- bound organelles.

    Cell theory: Okay, most scientific theories have 2 components: The first describes a pattern in the natural world, while the second identifies a mechanism or process that is responsible for creating that pattern. The complete cell theory, then, can be stated as follows: All organisms are made of cells, and all cells come from preexisting cells. — Cell membrane aka plasma membrane: A membrane that surrounds a cell, separating it from the external environment and selectively regulating passage of molecules and ions into and out of the cell. — Prokaryote: It’s a member of the domain Bacteria or Archea; a unicellular organism lacking a nucleus and containing relatively few organelles or cytoskeletal components. — Eukaryote: A member of the domain Eukarya; an organism whose cells contain a nucleus, numerous membrane-bound organelles, and an extensive cytoskeleton. It can be unicellular or multicellular. — Microtubule: A long, tubular fiber, about 25 nm in diameter, formed by polymerization of tubulin protein dimers; one of the three types of cytoskeletal fibers. It’s involved in cell movement and transport of materials within the cell. — Lysosome: A small organelle in an animal cell containing acids and enzymes that catalyze hydrolysis reactions and can digest large molecules. — Lipid bilayer aka phospholipid bilayer: The basic structural element of all cellular membranes consisting of a two-layer sheet of phospholipid molecules whose hydrophobic tails are oriented toward the inside and hydrophilic heads, toward the outside. — Endocytosis: This is a general term for any pinching off the plasma membrane that results in the uptake of material from outside the cell. Includes, for example, phagocytosis, pinocytosis, etc. — Exocytosis: Secretion of intracellular molecules (e.g., hormones, collagen), contained within membrane-bounded vesicles, to the outside of the cell by fusion of vesicles to the plasma membrane. ————————————–… @Asker: It seems like your learning about cell structure and function. This is really interesting stuff. You should open your book, study and read! I do hope these definitions help you to understand the basics, but there’s much more to it. Send me an email if you need more help or clarification. 😉

  • Eukaryotes are those organisms which contain true nucleus in their cell while Prokaryotes do not contain a true nucleus

  • Prokaryotic cell no nucleus and no cell organelles but ribosom 70s present 70s, whale the eukaryotic cell have cell organelles and have nucleus 80s ribosom present

  • Prokaryote: Unicellular; does not have membrane bound nucleus.

    Eukaryote: Multicellular; has membrane bound nucleus

  • Easy

    EUKARYOTES

    – they have true nucleus

    – examples: plant cells, animal cells, amoeba, etc..

    PROKARYOTES

    – don’t have true nucleus.

    – bacteria are the only prokaryotes

    There you go 🙂

  • in a projaryote cell, dna lies free in the cytoplasm in a structure called the nucleoid. Eukaryotic cells, DNA found in a nucleus with two membranes called a nuclear envelope
