The Nucleus Functions of the nucleus Storage of genes on chromosomes Transportation of regulatory factors & gene products via nuclear pores Separation of: DNA from cytosol Transcription from translation Organisation of: genes into chromosomes (to allow cell division) uncoiling of DNA to replicate key genes Production of: messenger RNA ( mRNA ) that code for proteins ribosomal RNA (rRNA) in the nucleolus Components within the nucleus Nuclear envelope: double membrane, each membrane is a phospholipid bilayer Nuclear pore: controls entry and exit from the nucleus e.g. of RNA proteins Nuclear lamina: a series of structural proteins found on the inner membrane of the nuclear envelope, provide structural support Nuclear matrix: scaffold proteins Nucleoplasm: viscous medium

Organelles Pro/Euk/Both Plant/Animal/Both Function Structural Features Nucleus Euk Both Contains DNA(nucleic acid) Control center of cell. Builds ribosomes(in nucleolus) Sphere. Has a membrane. Contains nucleolus Cell Membrane Both Both Regulates materials entering/leaving, protects and supports cell Phospholipid bi-membrane with proteins suspended throughout. Cytoplasm Both Both Fills the cell. Oranelles are found in it. Vacuole and Vesicle Euk Both Store materials Membrane bound sacs Mitochondria Euk Both Convert chemical energy in food to usable compounds. Turned into ATP. Second largest, Double layered outer membrane is smooth, inner membrane is folded Ribosomes Both Both

Name Function Description Cell Membrane The membrane at the boundary of every cell that acts as a selective barrier regulating the cells chemical composition. Cytoplasm The Cytoplasm offers support to the cell and speeds up inter-cellular travel. It allows the cell to take up 3-dimensional space and the cell's many organelles to "float" freely throughout. Mitochondria Where the cell creates most of the energy (ATP), also known as the ?powerhouse? of the cell. Nucleus This is where all the DNA is kept and translated into mRNA. Golgi Apparatus Stores and sends out proteins using vestical transport. Lysosomes Filled with digestive enzymes, Lysosomes function to get rid of waste and break down large macromolecules.
