Prokaryote Organelles: Nucleoid Region: The region in a prokaryotic cell consisting of a concentrated mass of DNA. (The “nucleus” of a prokaryotic cell) The nucleoid instructs all the organelles on what to do. Ribosome: A cell organelle consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus. (Make proteins from amino acids) The nucleoid controls the ribsomes and specifies

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped

p.92\ a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.

The debate between whether a virus is living or nonliving has been going on for years. In order to answer this question‚ one must have background knowledge relating to the current cell theory‚ the differences between prokaryotes and eukaryotes‚ and the structures and functions found within cells. Once this knowledge is known‚ a person is then able to give their opinion in the debate. In the 1800s‚ the cell theory was developed. This theory states that cells are found in all living things making them

The theory of endosymbiosis is that eukaryotes may have developed some of their internal cell structures/organelles from one cell engulfing another cell and then both developing a type of symbiotic relationship. Each engulfed cell would eventually serve a specialized function in support of the new single eukaryotic cell and eventually neither portion would be able to exist independently. This theory was originally developed by Lynn Margulis and there have been various discoveries that have supported

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated
