What is microorganisms in short?

An organism that can be seen only through a microscope. Microorganisms include bacteria, protozoa, algae, and fungi. Although viruses are not considered living organisms, they are sometimes classified as microorganisms.

Is virus a microbe?

Microorganisms can be bacteria, fungi, archaea or protists. The term microorganisms does not include viruses and prions, which are generally classified as non-living. There is currently a great deal of discussion about the organisation and classification of life, particularly in the study of microorganisms.

What is the difference between molecular biology and molecular genetics?

Like Biochemistry, Molecular Biology deals with the structure and function of proteins and how genes are expressed in cells. Genetics covers most of the same genetic parts of Molecular Biology and also includes a non-molecular part like evolutionary Genetics, population Genetics etc.

Where are microorganisms not found?

Living beings, especially microorganisms, have a surprising ability to adapt to the most extreme environments on Earth, but there are still places where they cannot live. European researchers have confirmed the absence of microbial life in hot, saline, hyperacid ponds in the Dallol geothermal field in Ethiopia.

What are antibiotics in short answer?

An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria.

How Viruses are formed?

Viruses may have arisen from mobile genetic elements that gained the ability to move between cells. They may be descendants of previously free-living organisms that adapted a parasitic replication strategy. Perhaps viruses existed before, and led to the evolution of, cellular life.

What are the 4 types of microorganisms?

The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below.

  • bacteria.
  • fungi.
  • algae.
  • protozoa.
  • viruses.

What are AntiBiotics Class 8 examples?

They are:

  • Penicillins.
  • Cephalosporin.
  • Macrolides.
  • Fluoroquinolones.
  • Sulfonamides.
  • Tetracyclines.
  • Aminoglycosides.

What are the two main types of antibiotics?

The main types of antibiotics include:

  • Penicillins – for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin.
  • Cephalosporins – for example, cefaclor, cefadroxil and cefalexin.
  • Tetracyclines – for example, tetracycline, doxycycline and lymecycline.
  • Aminoglycosides – for example, gentamicin and tobramycin.

What are Class 9 antibiotics?

Antibiotics are the medicines that inhibits the growth or kills the bacteria cauisng microbes by blocking the pathway for bacterial synthesis but doesnot affect its own pathway. The antibiotics block the biochemical processes used by bacteria to build cell wall that protects them.

What are antibiotics give example?

Antibiotic is a chemical secreted by microorganisms (bacteria or fungi) that kills or hinders the growth of some kinds of bacteria. Examples. Penicillin and streptomycin.

What are AntiBiotics for Class 8?

AntiBiotics are the chemical substances produces from microorganisms like bacteria, and are used as a medicine to kill or to stop the growth of the disease-causing microorganisms.
