![]() ![]() Morphology not only indicates the shape of a bacterial cell but also determines its pathogenicity. This microorganism can be chemoautotrophs, photoautotrophs or parasites. The cells of bacteria may consist of external attachments like flagella, cilia, etc. The main component of the cell wall of a bacterium is peptidoglycan or murein.ĭifferent shapes of bacteria form a characteristic feature of a particular bacteria species. The diameter of each bacteria cell is ~1µm (10^-6 m).Ī bacteria cell is covered by a rigid cell wall which helps in providing constructional integrity. In comparison to human cells, bacterial cells are ten times smaller. Notably, it is not wrapped for the formation of chromatin, like in the case of eukaryotic cell. The DNA of bacteria is found in cytoplasm. It also lacks membrane-bound cell organelles. There are different bacteria shapes, sizes and arrangements. To know more about this microscopic organism take a look at the following features of the same: An essential characteristic of bacteria is that it can grow in extreme conditions such as snow, oceans, hot springs, etc. They are single-celled, prokaryotic organisms which are found everywhere. So, you can refer to the below mentioned important notes of biology for NEET shapes of bacteria for fast and adequate revision. ![]() Since you have just a few weeks left before the examination, revising the chapter top to bottom can be difficult. As a part of the NEET curriculum, it is considered one of the most vital topics where various bacteria shapes cover the maximum part. ![]() Shapes of Bacteria: Important Notes on Biology for NEETīacteria are the most abundantly existing microorganisms on Earth. ![]()
