Bacterial cells can have various external features. Describe the functions of each of the following: a. Flagella b. Fimbriae C. Capsule 10. What is the "nucleoid" region of the bacterial cell and why is it called that name?

Answer 1

Solution

Archaebacteria and eubacteria are two categories of kingdom monera.

Nucleiod is the irregular shape genetic material region present in prokaryotic cell without membrane.

ac T solution -88) Desenbe a categories of bacteria found in moneran kingdom. Categories - Archaebactessa Eubacteria * Archaebacteria - also called as Ancient bacteria. They are evolved very early on earth primitive environments billions years ago. some are auto- trophic, heterotrophic, some living on boiling hot spoing, acidic environment, intestine of Animals sewage and swampy mud. They create foul smell and some are live in anaerobic envinnment There extremophiles Cextreme hot, acidic, anaembic) natuse keep them different from eubacteria. * Eubacteria - They are the true bacteria. They are responsible for addition of oxygen in earths primitive environment billions of years most of the enbacteria not live in extreme environment. most can perform the food synthesis having peptidoglycan cell wall. They are found on surface of water to make energy to make fad and oxygen

Examples of Archaebacteria are - Methanogens - Halophiles - Thermoacidophiles Examples of Eubacteria - cocci - bacilli spirilla - 810) Nuclecid Region - ef is region present in the prokaryotic cell, which is made up of irregular shape of genetic materialo Nuclecid contanis DNA, RNA and enzymes. It is without membrane hence called as Nuclearl rather than nucleus. - if genetic material is enclosed inside membrane then it is called as Nucleus. if genetic material is not enclosed inside nuclear membrane then it is called as Nucleoid.
