shapes of bacteria class 11|cocci|bacilli|spirochete|vibrio
2Aoa! MY name Is Ehsan and welcome to Biology with Ehsan
In this lecture we discussed the diversity amongst bacteria on the basis of shapes. The lecture includes cocci , which are spherical in shape, bacilli,which are rod shaped and spirilli which are spiral in shape.
The Cocci can be further classified as diplococci, tetrad , sarcinae, streptococcus and staphylococcus. Vibrio are coma shaped bacteria
The Lecture shapes of bacteria is important for biology class 11 students especially for federal board biology class 11 students.
There are three basic shapes of bacteria: coccus, bacillus, and spiral.
Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus.
The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.
The spiral shape can appear in several forms: vibrio, spirillum, and spirochete.
The metric unit micrometer (1/1,000,000 or 10-6 of a meter) is used to measure bacterial size.
