Document Summary

Function: cell boundary and involved in various membrane transport mechanisms: plasma membrane: Structure: bilayer of phospholipids, glycolipids and glycoproteins: microvilli: Function: allow greater surface area for absorption: cilia: Structure: numerous short extensions containing microtubules: flagellum: Structure: long extension of sperm cell containing microtubules: nucleus: Structure: double membrane boundary of nucleus with pores; continuous with rough er: nucleolus: Structure: nonmembranous body containing ribosomal rna and protein: chromatin: Structure: strands of dna and protein: cytoplasm: Structure: contents between plasma membrane and nucleus containing cytosol fluid. Function: dna represents genetic control for protein synthesis. Function: site of protein synthesis with ribosomes; cellular transport: membrane-bound organelles: Structure: organelles possessing a membranous covering: rough endoplasmic reticulum: Structure: extensive membrane network with attached ribosomes: smooth endoplasmic reticulum: Structure: extensive membrane network lacking ribosomes: mitochondria: Structure: possess a double membrane with folded inner membrane: golgi apparatus (complex): Structure: series of flattened sacs often near nucleus: vesicles: Function: packaging side of glycoproteins for transport and secretion.
