Intracellular Components Terms Actin - A very abundant protein in eukaryotic cells that is the main component of actin filaments. Actin Filaments - Approximately 5-9 nanometers in diameter. Provide structural support to the plasma membrane. As a cytoskeletal protein provides for movement of organelles within cells. Centromere - A round structure that holds together sister chromatids. Centrosome - A region of the cell near the nucleus from which microtubules sprout. Centrosomes are not found in all cells. Centrosomes are comprised of two centrioles. Chromosome - A structure composed of DNA and proteins containing all the genetic material of a cell. Found in the cell nucleus. Cytoplasm - A fluid found in the main compartment of eukaryotic cells. Includes everything outside the cell nucleus but the organelles and the cytoskeleton. The main component is cytosol. Cytoskeleton - A system of protein filaments found throughout the cytoplasm of eukaryotic

Unformatted text preview: cells that help provide for cell structure. Composed of actin, intermediate filaments, and microtubules. Cytosol - The main component of the cytoplasm that fills the main compartment of eukaryotic cells. Endoplasmic reticulum - A membrane-bound organelle found in eukaryotic cells. Makes direct contact with the cell nucleus and, since it is dotted with ribosomes, is the site of lipid and protein synthesis . Comes in two forms, smooth and rough. Endosome - A membrane-bound organelle found in eukaryotic cells. Responsible for delivering molecules to the lysosome for digestion. Eukaryote - An organism composed of one or more cells with defined intracellular components including a nucleus and cytosol. Includes all organisms except bacteria and viruses . Golgi apparatus - A membrane-bound organelle found near the cell nucleus in eukaryotic cells. Responsible for sorting and packaging proteins for secretion to various destinations in the cell....
