In this BYJUâS Champions series, your Biology educator, Aishwarya Maâam, discusses an important concept, Introduction to Bacteria and its types, from your class 8 Science chapter, Microorganism.
Microorganisms or microbes are tiny living organisms that are not visible to the naked eyes. One such very common type of microbes is bacteria. Bacteria are prokaryotes. They lack well-defined nuclei and membrane-bound organelles. Bacterias may seem insignificant in nature, but they are essential to human life and the life on this planet, Earth. There are good bacteria and bad bacteria. While of course, the harmful bacteria cause human diseases including tooth decay and black plague, the good bacteria help fight bad bacteria in your body. Good bacteria help our bodies to digest food and absorb nutrients. They also help in producing several vitamins in the intestinal tract. Join this class to learn more about bacteria and their types.

Ma'am what is the name of this app
Procaryotic
What is flagella
Please reply
Flagella are microscopic hair-like structures involved in the locomotion of a cell.
Hi
Homework answer:
Cocci can grow in chains, clusters or pairs. Based on the arrangement of cocci cells, they can be further divided into -
Streptococci- cocci arranged in chains. E.g., Streptococcus mutans
Diplococci- cocci arranged in pairs. Eg., Neisseria gonorrhoeae
Monococci- single cocci.
Staphylococci- clusters of cocci. Eg., Staphylococcus aureus
Tetrads- cocci in groups of four. Eg., Pediococcus
Sarcina- cocci in groups of eight. E.g., Sarcina ventriculi
Streptococci and diplococci mostly occur due to the non-separation of daughter cells after cell division. Sarcinae are organised in cubical pockets as cell division alternates amid three perpendicular planes.
Thank you mam, this session was really amazing. Thank you mam it made me understand much better than before. This is awesome!!!đđ
Awesome Advikađ Glad you liked the session!
