1
an extensive intracellular membrane system whose functions include synthesis and transport of lipids and, in regions where ribosomes are attached, of proteins
2
a network of stainable cytoplasmic fibers, rods, granules, etc., that can collect proteins and secrete them outside the cell : also Golgi body
3
a small spherical or rodlike body, bounded by a double membrane, in the cytoplasm of most cells: contains enzymes responsible for energy production
4
a very thin membrane, composed of lipids and protein, that surrounds the cytoplasm of a cell and controls the passage of substances into and out of the cell Also called: plasmalemma, plasma membrane
6
a small rounded body within a resting nucleus that contains RNA and proteins and is involved in the production of ribosomes Also called: nucleole
8
any of numerous minute particles in the cytoplasm of cells, either free or attached to the endoplasmic reticulum, that contain RNA and protein and are the site of protein synthesis
9
a fluid-filled cavity in the cytoplasm of a cell
10
(in the cells of eukaryotes) a large compartment, bounded by a double membrane, that contains the chromosomes and associated molecules and controls the characteristics and growth of the cell
11
the solution of proteins and metabolites inside a biological cell, in which the organelles are suspended
