fimbriae and pili both are surface structure of bacteria but fimbriae are always found much in number having 3to25 nm diameter and 0.5 to 20 micrometer in length.
whereas pili are always found less in no generally 2 or more .
fimbriae are specialized for attachment of bacteria to its host as in case of pathogenic bacteria salmonella typhimurium , Nisseria gonorrhoea , bordella pertussis.
whereas pili are responsible for sexduction (conjugation) in bacteria ,and serves as receptors for certain viruses.
both fimbriae and pili are divided in many classes according to work they perform such as twiching motility of bacteria is observed in type 4 class..
besides these both are always noticed in gram (-) bacteria only exception cornibacterium renale (gram+).
What else can I help you with?
What are bacterial structures involved in the passage of DNA into or out of the cell?
Bacterial structures involved in the passage of DNA into or out of the cell include pili, which facilitate the transfer of DNA between bacterial cells through conjugation, and the cell membrane, which allows for DNA uptake during transformation or release during secretion. Additionally, some bacteria use specialized structures such as plasmids or phages to transfer genetic material between cells.
What is the major differences between a bacterial cell and the cell of other organisms?
All bacterial cells do not have a nucleus but the cells of other animal have nucleus which is usually spherical or oval in shape inside it there are chromosomes that form a dense tangle referred to as chromatin.
Does flagella allow bacteria to conjugate?
No, flagella are used for movement, not for conjugation in bacteria. Conjugation involves the transfer of genetic material between bacteria through a pilus, a specialized appendage.
What is the finger-like processes that work to propel the discharge ovum into the tube are called?
The Infundibulum. The end closest to the ovary forms an expanded funnel, or infundibulum, with numerous fingerlike projections that extend into the pelvic cavity. The projections are called fimbriae.Fimbriae drape over the surface of the ovary, but there is no physical connection between the two structures.
What are the main difference between mitochondrial and chloroplast DNA's?
The ribosomes of chloroplasts closely resemble bacterial ribosomes, while mitochondrial ribosomes show both similarities and differences that make their origin more difficult to trace.
Can the possession of flagella by bacteria be utilized for classification purposes explain?
Yes, the presence and arrangement of flagella on bacteria can be used for classification purposes. Different bacterial species may have unique flagella patterns, such as number, location, and movement. Studying flagella can help differentiate between bacterial strains and aid in taxonomic classification.
What is the Hairlike structure on the surface of many bacteria?
Flagella are long hair-like structures and Cillia are short hair-like structures. They can both help with the movement of the bacteria and cillia could stop foreign material entering the bacteria cell.
What are the differences between flagella and cilia in terms of their structure and function?
Flagella and cilia are both hair-like structures found in cells, but they have distinct differences in terms of structure and function. Flagella are longer and fewer in number, while cilia are shorter and more numerous. Flagella typically move in a whip-like motion to propel the cell, while cilia have a back-and-forth motion to move substances along the cell surface. Both structures are made up of microtubules, but the arrangement and length of these microtubules differ between flagella and cilia.
What are the main differences between cilia and flagella in terms of their structure and function?
Cilia and flagella are both hair-like structures found in cells, but they have some key differences. Cilia are shorter and more numerous, while flagella are longer and usually found singly or in pairs. In terms of function, cilia are involved in moving substances along the cell surface, while flagella are typically used for cell movement.
What part of bacterial cells aids in movement?
Motile
What are the difference in the flagella in prokaryotic and eucarkaryotic?
Eukaryotic flagella are quite different in structure and function to prokaryotic flagella.Bacterial flagella (as opposed to archaeal flagella - go to http://en.wikipedia.org/wiki/Flagellum#Archaeal to investigate differences between bacterial and archaeal flagella) are composed of the protein flagellin, which is coiled around into a stiff filament. Movement of a bacterial cell is generated by rotation of the filament, a bit how like a propellor works. Reversing direction of rotation can change direction of movement.In eukaryotic flagella, the structure is more complex. The base of the eukaryotic flagella houses the foundation of the structure. Nine microtubule groups, each consisting of three microtubules, form the base of the flagella. Further away from the cell, the flagella is made up of two microtubule's connected by a bridge. Radial spokes branch out to nine pairs of microtubules that form a circle around a flagella transverse section (if you chop it in half and look at the exposed inside).A eukaryotic flagella moves its cell by sliding adjacent pairs of microtubules, which causes the flagella to bend. This bending creates movement. To see a good example, watch this video: http://www.britannica.com/EBchecked/topic-video/209243/16501/Movement-of-eukaryotic-flagella-in-real-time-and-slow-motion
What is the difference between cilia and flagella in terms of their structure and function?
Cilia and flagella are both hair-like structures found on cells, but they have some key differences. Cilia are shorter and more numerous, while flagella are longer and fewer in number. In terms of function, cilia are primarily involved in moving substances along the cell surface, while flagella are used for cell movement.
What is the differences between viral and bacterial water-born disease?
The viral water-borne diseases cannot be treated by the antibiotics while the bacterial water-borne diseases can be treated by the antibiotics.
What are bacterial structures involved in the passage of DNA into or out of the cell?
Bacterial structures involved in the passage of DNA into or out of the cell include pili, which facilitate the transfer of DNA between bacterial cells through conjugation, and the cell membrane, which allows for DNA uptake during transformation or release during secretion. Additionally, some bacteria use specialized structures such as plasmids or phages to transfer genetic material between cells.
What is the relationship between flagella and trichomoniasis?
Trichomoniasis uses flagella for movement. This movement is very distinctive under the microscope.
What are the tiny hairs on the bacteria called?
Wiskers Theyre called cilia. Like the tiny hairs in your nose.
