Sedimentary Rock Examples. Common clastic sedimentary rocks are listed on the table below. They are listed by grain size in decending order. Grain size is one factor in classifying sedimentary rocks .Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window.
THE PROKARYOTIC CELL: BACTERIA. 1. There are three basic shapes of bacteria: coccus, bacillus, and spiral. 2. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus.acterial cell shape is determined primarily by a protein called MreB. MreB forms a spiral band â a simple cytoskeleton â around the interior of the cell just under the cytoplasmic membrane. It is thought to define shape by recruiting additional proteins that then direct the specific pattern of bacterial cell growth.
The second microbe that is among the smallest would be bacteria and then probably protists, as a generalization, after that (protists and bacteria have wider ranges of sizes than viruses).Bacteria are microscopic living organisms, while the viruses are non-living sub-microscopic organisms. microbe is an organism that can be seen using a microscope. They  include fungi, bacteria, viruses, archea and protists. All except  fungi consist of a single cell, althou â¦ gh microbe diversity is vast.  Microbes are the causes of many diseases, such as the common cold,  the black death and malaria.
