The Parts of Cells – Student Worksheet Table 1. Parts involved in Protein Synthesis found in almost ALL eukaryotes Organelle 1 Where Function # Membrane Layers Parts Nucleus Connected to rER by endomembrane system cell control, genetic storage, mRNA synthesis 2: nuclear envelope with pores; shape maintained by nuclear lamina chromatin, nucleolus; sometimes chromosomes Ribosome 1 Free in cytosol, bound to rER protein synthesis; translates mRNA to proteins 0 proteins and RNA Rough endoplasmic reticulum (rER) connects to nuclear membrane at one end, may vesiculate into sER or vesicles at other end Makes & exports plasma membrane, folds & assists protein assembly, exports proteins 1 cisternae and their lumena, the cisternal spaces Golgi apparatus Faces rER at cis end a system of “factories” that synthesizes many carbohydrates; also finishes rER products, adds signalling proteins to vesicles 1 cisternae and their lumena, the cisternal spaces 1 ribosomes are not membrane-bound, and thus are not organelles by many people’s definition
