But there may be others such as helically twisted cylinders, cylinders curved in one plane and unusual morphologies. Arrangements include pairs, tetrads, clusters, chains and palisades. Morphology of Bacteria- Sizes, Shapes, Arrangements, Examples Bacterial Size. Figure: The relative sizes of various microscopic and nonmicroscopic objects. Note that a typical virus Bacterial Shape. Most of the bacteria have a rigid cell wall that provides a definite shape to the bacteria z The morphological study of bacteria requires the use of microscope like.

Microbiology is the microscopic study of micro-organism like bacteria, viruses and protozoa.
They lack rigid cell wall, they are viable, grow and multiply on suitable culture media. They are soft protoplasmic bodies, spherical or disk-like. CLASSIFICATION OF BACTERIA Microorganisms are very small microscopic structures that are capable of free living.

Characteristics of bacterial colonies Colony morphology can sometimes be useful in bacterial identification. Colonies are described on the basis of size, shape, texture, elevation, pigmentation, and effect on growth medium. In this blog post, you will find common criteria that are used to characterize the bacterial growth.
Overproduction of FtsZ two to seven folds can induce mini-cell formation in wild-type cells, cell division is initiated earlier in the cell cycle (Ward and Lutkenhaus, 1985). Depending on their shape, bacteria are classified into several varieties Cocci (from kokkos meaning berry) are spherical or oval cells Bacilli (from baculus meaning rod) are rod-shaped cells L-Forms of Bacteria (L-Phage Organisms): These are abnormal forms derived from bacteria of abnormal morphology (cocci, bacilli, vibrio) due to variation in the laboratory. They lack rigid cell wall, they are viable, grow and multiply on suitable culture media.
