Minute cells are found in mycoplasma. Mycoplasma is Correct Answer Bacteria

The correct answer is Bacteria.

HintMicrobes (Micro-organisms) : These are single-celled organisms that are invisible to the naked eye.”

  • In order to study them, a Microscope (Compound or Electron microscope) is used.
  • They make up almost 60% of the earth’s living matter. Some microbes are useful and some are harmful.
  • Microbes include - Bacteria, Fungi, Viruses, Green algae, Archea, Eubacteria, and Protista.

Explanation

Mycoplasma 

    Figure. Structure of Mycoplasma

  • They belong to the genus of bacteria.
  • They are the smallest bacterial cells yet discovered, can survive without oxygen, and come in various shapes. 
  • They completely lack a cell wall.
  • They are the smallest living cells known and can survive without oxygen.
  • Many Mycoplasma is pathogenic in - animals and plants.
  • Ex. M. genitalium (Cause infection of genital), M. pneumoniae (cause atypical pnemonia) 

Additional Information

I] Virus

  • They are neither considered living or non-living.
  • They are non-cellular microorganisms, composed of protein, nucleic acids, and lipids.
  • They are the tiniest among microbes and sizes ranging from 20 nanometers to 250 nanometers.
  • Viruses exist almost everywhere, and they can infect any living organism. They change their genetic material continuosly and developes resistance against vaccines. This ability of viruses makes them deadly (life-threatening).
  • Examples. Influenza, HIV

II] Fungi

  • They are - unicellular or multicellular non-photosynthetic organisms.
  • Their cell wall is made of chitin.
  • These are saprophytic and parasitic in nature.
  • Examples. Yeast, Candida

III] Bacteria :

  • They are unicellular, microscopic, prokaryotic microorganisms that contain no true nucleus.
  • They have cell wall and flagella (tail like structure) for locomotion.
  • They are found in different shapes - Cocci (round shape), bacilli (rod shape),, cocco-bacillii (round-rod combined shape), Vibrio (comma shape), Spirillum (spiral shape)
  • Examples. Lactobacillus, Streptococcus pneumoniae 

IV] Green Algae :

  • These are the micro-organisms that are grouped in the kingdom Protista. They are plant-like, in that they are able to manufacture energy from sunlight using chlorophyll pigments.
  • The plant body may be unicellular, colonial or filamentous.
  • The members of Chlorophyceae (Group of Algae) are commonly called Green algae.
  • Examples. Chlamydomonas, Chara.
