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.
Microbes include bacteria and archaebacteria, protists, some fungi and even some very tiny animals that are too small to be seen without the aid of a microscope. Viruses and the recently discovered prions are also considered microbes.The term microbe is short for microorganism, which means small organism.or one thing, fungi cannot synthesize their own food via photosynthesis, like plants do, but instead they feed off of other organisms as do animals. Plants. Plants are organisms that can obtain energy from sunlight. All plants are relatively large, and hence none are generally considered microbes.
