Nucleus/Nucleolus Structure Double membrane (nuclear envelope) with nuclear pores Chromatin Nucleolus Function Stores hereditary info (DNA) Makes RNA (which makes proteins) Makes ribosomes (nucleolus) Cell Type Eukaryotic Cells Plant Cells Animal Cells ROUGH ER Structure Internal membrane is a system of folded sacs and tunnels Has ribosomes on it Function Intracellular highway for molecules to move around and out of the cell Makes proteins and other cell components Cell Type Eukaryotic Cells Plant Cells Animal Cells SMOOTH ER Structure Internal membrane of systems of folded sacs and tunnels NO ribosomes Function Intracellular highway Storage area for proteins Cell Type Eukaryotic Cells Plant Cells Animal Cells RIBOSOMES Structure Function Made of proteins and RNA No membrane Made in nucleolus Location of protein synthesis Free ribosomes make proteins used by the cell Ribosomes on rER make proteins for export to other cells Cell Type Prokaryotic Cells Eukaryotic Cells Plant Cells Animal Cells GOLGI APPARATUS Structure Function Stack of membranes or sacs filled with fluid Processes, packages, and secretes materials made in the ER Cell Type Eukaryotic Cells Plant Cells Animal Cells MITOCHONDRIA Structure Double membrane Have own DNA Very numerous in high requirement cells (muscles) Function Powerhouse of the cell (energy) Transfers chemical energy into ATP to be used as energy for life functions Cell Type Eukaryotic Cells Plant Cells Animal Cells CHLOROPLASTS Structure Double membrane Contains DNA Contains green pigment (chlorophyll) Function Responsible for photosynthesis (conversion of sunlight into chemical energy) Cell Type Eukaryotic Cells Plant Cells LYSOSOMES Structure Spherical organelles Contain enzymes Function Digestion of: Organic molecules Old organelles Foreign substances Cell Type Eukaryotic Cells Plant Cells Animal Cells CYTOPLASM aka CYTOSOL Structure Fluid between cell membrane & organelles Contains water, salts, organic compounds Function Aids in movement Cell Type Prokaryotic Cells Eukaryotic Cells Plant Cells Animal Cells CYTOSKELETON Structure Network of long protein strands Located in the cytosol No membranes Function Support cell by giving shape and organization Help with movement of organelles in the cytosol and cell movement Cell Type Eukaryotic Cells Plant Cells Animal Cells CELL MEMBRANE Structure Lipid bilayer with carbs and proteins Function Selectively permeable Boundary and support for cell (protection) Cell Type Prokaryotic Cells Eukaryotic Cells Plant Cells Animal Cells CELL WALL Structure Wall outside membrane Made of cellulose Has pores Function Protect Support Cell Type Eukaryotic Cells: Plant Cells Prokaryotic cells VACUOLES Structure Membrane bound fluid filled organelles Function Stores: Water Proteins, carbs, salts Cell Type Eukaryotic Cells Plant Cells (large) Animal Cells (small)
