ribosomes - build proteins (connect the amino acids in primary structure), Gap Junction - tubes between cells that allow for cell to cell communication, microtubule - Maintain cell shape, Movement of materials: form a monorail inside cell, Motar proteins carrying vesicles travel along the microtubules to destination, Mitotic spindle, Cilia and Flagella, smooth ER - Makes Lipids, Builds vesicles, horomone manufacture (testes), detoxifies cells in liver, stores calcium ions in muscle., desmosome - Hold cells together into sheets , cytoskeleton - maintain cell shape, transport materials, movement of cells, junctions, Plasma Membrane - Provides a barrier for the cell, Regulates flow of water and waste and nutrients, (for eukaryotic organelles) Provides enclosed environment within cell for metabolic processes, golgi apparatus - Protein processing (trimming of carbohydrate chains, altercation of proteins), Production of polysaccharide, sorts proteins (adds phosphate group tags), Ships proteins to appropriate destinations , mitochondria - to produce energy for cells (ATP), Cellular respiration (oxygen is used to convert the products of glucose breakdown into ATP), rough ER - Folding and processing of secretory proteins, attatches carbohydrates to proteins, makes phospholipids and membrane , nucleolus - used to create ribosomes , lysosomes - Digest foreign materials and old organelles. (found in animals), peroxisome - Sacs of membranes containing several types of enzymes, Breaks down fatty acids to be used for energy, Detoxify alcohol and toxins (in animals), Coverts fatty acids to sugar for seedling (in plants)., Microfilament / Actin Filament - -Maintain cell shape, Make up core of microvilli for absorption, cleavage furrow for cell division, movement of cell: muscle contraction/ pseudopodia: amoebas and macrophages, Cytoplasmic steaming in plants, tight junction - form tight seals to prevent leakage , Nucleus - Houses and protects cell's DNA, cell wall - maintain shape, protect cell, prevent excessive uptake of water, Intermediate Filament - Maintain cell shape, Hold organelles in place, Remain after cell's death (keratin), Plasmodesmata - -channels that connect cells, continuous cytosol flow ,
