Bacteria can use flagella in different ways to generate different kinds of movement many bacteria (such as e coli) have two distinct modes of movement: forward movement (swimming) and tumbling.
Different species of bacteria are classified into five categories according to their shapes: cocci, bacilli, vibrios, spirochaetes or spirilla cocci are spherical, while bacilli are rod-shaped vibrios are shaped like commas, spirochaetes like corkscrews and spirilla like spirals. A few different criteria are used to classify bacteria they can be distinguished by the nature of their cell walls, by their shape, or by differences in their genetic makeup the gram stain is a test used to identify bacteria by the composition of their cell walls.
Different kinds of bacteria are classified by physical characteristics biology bacteria are classified in a number of different ways the traditional and most commonly used classification system is gram stain, but bacteria are also classified based on shape and other physical characteristics, such as growth requirements bacteria can be.
Name 3 ways bacteria can be classified shape, environment, cell wall what is the shape of coccus round what is the only non-membrane bound oganelle found in the cytoplasm of bacteria ribosomes bacteria have how many chromosomes 1 other than the cell membrane, name one thing that bacteria and eukaryotes have in common. 1 cover different classification schemes for grouping bacteria, especially the use of the gram stain 2 describe the different types of bacteria 3 discuss bacterial structure and the function of the different bacterial components 4 discuss the distinguishing characteristics of gram positive and gram negative bacteria.
Bacteria are classified in many ways most bacteria are classified by their shape, cell wall, movement, eating, and breathing the most useful technique of classification would be the gram stain the gram stain distinguishes between differences in the cell wall composition of bacteria (gram positive or gram negative.
