Explain the Prokaryotic Cells in details?
Prokaryotic Cells: Cells that lack a membrane-bound nucleus and have very few distinguishable internal structures when observed with microscopes are called prokaryotes, from the Greek meaning before nuclei. Bacteria and cyanobacteria (formerly called blue-green algae), for example, do not contain a nucleus or any of the organelles found in eukaryotic cells.
Bacterial cells are very different from the cells of higher organisms. In the first place, they are all much smaller, one tenth the size of eukaryotic cells. Most bacterial cells are roughly cylindrical, ranging in size from 1 to 2 micrometers in diameter, and up to 10 micrometers long, or about the same size as animal mitochondria. The nucleus of a typical prokaryotic cell is a fibrous mass of DNA found in a structure called a nucleoid. When some bacteria cells divide by fission, they form an extension of the plasma membrane called a mesosome that extends inward to help separated the duplicated DNA.
Immobilisation of cells Immobilisation of cells enables Re-use of biomass by rotation of cells Separation of cells from the medium and Leaching of metab
