The cytoplasm

cytosol

intracellular fluid, nutrients, ions, and wastes

orgaelles

performs cellular functions

3 components of cytoskeleton

microfilaments, intermediate filaments, microtubules

microfilaments function

anchor cytoskeleton to plasma membrane, change the shape of the cell

intermediate filaments function

strengthen cells and help maintain its shape, stabilize position of organelles and cell itself, most durable of all filaments

microtubules function

primary component of cytoskeleton, can help change shape of cell, can help shuttle small vesicles and organelles around a cell, aids in cell division- moves chromosomes, form structural components of organelles, largest of the filaments

centrioles function

form spindle fibers apparatus associated with movement of chromosomes

cilia function

beat to move fluid or secretions across cell surface, waves are synchronized and can move materials effectively

ribosomes function

responsible for protein synthesis

mitochondria function

produce energy

rough ER function

modifying and packaging proteins for export to golgi

smooth ER

synthesis of lipids and steroid hormones, storage of glycogen and Ca++

golgi apparatus function

receives newly modified proteins from ER, proteins are modified and packaged

lysosome function

breakdown large macromolecules

peroxisome function

absorb and breakdown fatty acids and other organic compounds, neutralizes H2O2 formed by fatty acid breakdown
