(Yes or No) Is it found in:CellularOrganelleDescription of StructureDescription of FunctionProkaryotesEukaryotes:AnimalCellsEukaryotes:PlantCellsCytosolJelly-like substance that contains 70% water, but that is thickened with ions, salts, and dissolved polar biomolecules (like enzymes).Substance that resides within the cell’s plasma membrane, but outside of all other cellular organelles and/or compartmentsyesyesyesNucleoidThere is no membrane around theprimary DNA, therefore this region takeson an irregular shapeThe circular DNA chromosome of these cells compacts with the help of some associated proteinsand resides in a region of the cell that is known as the nucleoid.No Yes Yes NucleusA darkly stained region within the nucleus Surface is composed of a double-phospholipid bilayer known as the nuclear envelope.Organelle thatencapsulates the DNA ofeukaryotic cells. The surface has integral proteins that keep the two bilayers connected and that createnuclear poresthrough which molecules (such as RNA)can pass.DNA is protected from enzymes in the cytosol.Site of RNA production from DNA(transcription)No Yes Yes RibosomesNo membrane to this cellular component, but is instead made up of a combination of proteins and rRNA (ribosomal RNA)Made of two pieces (or subunits): Large and Small Takes information from mRNA and assembles aminoacids into a protein (translation).Can be free-floating in thecytosol or attached to otherorganelles in eukaryotic cellsYes Yes Yes Rough Endoplasmic ReticulumOrganelle attached to the nucleus that is composed of stacks of flattened, circular membranes that are much like the outer cell membrane.Known as “rough” because the surface of these membranes are studded with ribosomes.
