Cells Building Blocks of LifeMicrovilli are finger-like projections on the outer-surface of the cellBiolsci.orgMost prokaryotes are the smallest of all organisms ranging from 0.5 to 2.0m in diameter.[13]The biological information contained in an organism is encoded in its DNA sequence.[3] RNA is used for information transport (e.g., mRNA) and enzymatic functions (e.g., ribosomal RNA)Organelles are parts of the cell which are adapted and/or specialized for carrying out one or more vital functions, analogous to the organs of the human body (such as the heart, lung, and kidney, with each organ performing a different function).[3] Both eukaryotic and prokaryotic cells have organelles, but prokaryotic organelles are generally simpler and are not membrane-boundGolgi apparatus: The primary function of the Golgi apparatus is to process and package the macromolecules such as proteins and lipids that are synthesized by the cellRibosomes Ribosomes is the site for protein synthesis where thetranslation of the RNA takes place.As protein synthesis is very important to the cell,ribosomes are found in large number in all cells.Ribosomes are found freely suspended in the cytoplasmand also are attached to the endoplasmic reticulumThis leads to growth in multicellular organisms (the growth of tissue) and to procreation (vegetative reproduction) in unicellular organisms b7dc4c5754
