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

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.
– they have true nucleus
– examples: plant cells, animal cells, amoeba, etc..
– 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
