LABELLED CELL

1) Nucleolus- dark-staining, spherical body in the nucleus that produces ribosomal subunits
2) Nuclear Envelope- double membrane that surrounds the nucleus and is continuous with the endoplasmic reticulum.
3) Ribosomes- RNA and protein in two subunits; site of protein synthesis in the cytoplasm, produces proteins
4) Vesicle-small, membrane-bound sac that stores substances within a cell
5) Rough Endoplasmic Reticulum-
6) Golgi Apparatus- organelle, consisting of flattened saccules and also vesicles, that processes, packages, and distributes molecules about or from the cell.
7) Cytoskeleton- internal framework of the cell, consisting of micro tubules, actin filaments, and intermediate filaments
8) Smooth Endoplasmic Reticulum
9) Mitochondrion- membrane-bounded organelle in which ATP molecules are produced during the process of cellular respriation
10) Vacuole- membrane-bounded sac that holds fluid and a variety of other substances
11) Cytoplasm- contents of a cell between the nucleus and the plasma membrane that contains the organelles
12) Lysosome- membrane-bounded vesicle that contains hydrolytic enzymes for digesting macromolecules 
13) Centriole- cell organelle, existing in pairs, that occurs in the centrosome and may help organize a mitotic spindle for chromosome movement during animal cell division
