- 1NucleusMost prominent organelle of
a eukaryotic cell.
Enclosed within two concentric membranes and contains DNA organized into chromosomes. - 2NucleolusLarge structure in nucleus where ribosomal RNA is transcribed and ribosomal subunits are assembled.
- 3Nuclear envelopeA double lipid bilayer also known as the nuclear membrane.
- 4MitochondrionMembrane-enclosed organelle, about the size of a bacterium.
Carries out oxidative phosphorylation and produces most of the ATP in eukaryotic cells. - 5Rough Endoplasmic ReticulumRegion of ER associated with ribosomes and involved in the synthesis of secreted and membrane-bound proteins.
- 6Smooth Endoplasmic ReticulumRegion of ER not associated with ribosomes, but involved in the synthesis of lipids.
- 7Endoplasmic ReticulumMembrane-enclosed component in the cytoplasm of eukaryotic cells, where lipids and secreted & membrane-bound proteins are made.
- 8RibosomeParticle composed of ribosomal RNAs and ribosomal proteins that associate with mRNA and catalyses the synthesis of protein (translation).
- 9Golgi apparatusMembrane-enclosed organelle in eukaryotic cells where the proteins and lipids made in the ER are modified and sorted for transport to other sites around the cell.
- 10Secretory granuleMembrane-enclosed organelle in which molecules destined for secretion are stored prior to release. Visible as small solid object due to darkly staining contents.
- 11Plasma membraneMembrane that surrounds a living cell.
- 12Cytoskeletal componentsSystem of protein filaments in the cytoplasm of a eukaryotic cell that gives the cell shape and the capacity for directed movement.
Most abundant components: actin filaments, microtubules and intermediate filaments
