= = =Tuesday 10/21/14 = =Keystone Vocabulary = = __Nucleus__ - A membrane‐bound organelle in eukaryotic cells functioning to maintain the integrity of the genetic material and, through the expression of that material, controlling and regulating cellular activities. = = __Chloroplast__ - An organelle found in plant cells and the cells of other eukaryotic photosynthetic organisms where photosynthesis occurs. = = __Ribosome__ - A cellular structure composed of RNA and proteins that is the site of protein synthesis in eukaryotic and prokaryotic cells. =   = = = =

= = =Wednesday 10/22/14 = =Keystone Vocabulary = = __Chromosomes__ - A single piece of coiled DNA and associated proteins found in linear forms in the nucleus of eukaryotic cells and circular forms in the cytoplasm of prokaryotic cells; contains genes that encode traits. Each species has a characteristic number of chromosomes. = = __Golgi Apparatus__ - An organelle found in eukaryotic cells responsible for the final stages of processing proteins for release by the cell. =

=Thursday 10/23/14 = =Keystone Vocabulary = = __Endoplasmic Reticulum__ (ER) - An organelle, containing folded membranes and sacs, responsible for the production, processing, and transportation of materials for use inside and outside a eukaryotic cell. There are two forms of this organelle: rough ER that has surface ribosomes and participates in the synthesis of proteins mostly destined for export by the cell and smooth ER that has no ribosomes and participates in the synthesis of lipids and steroids as well as the transport of synthesized macromolecules. =
