Question

Some hyper thermophilic organisms that grow in highly hot environments from 60°C and upwards belong to which of the following groups?
(a) Liverworts and yeasts
(b) Eubacteria and archaea
(c) Cyanobacteria and diatoms
(d) Protists and mosses

Answer 1

Hint: Hyperthermophiles or Hyperthermophilic are those organisms which can grow at a very high (hot) temperature (80°C) by Stetter in 2013 or can grow above (90°C) BY Adam and Kelly in 1998. They need high temperatures or extremely very hot climates because they have a special type of enzyme that can perform various functions at a very high temperature. At present about 90 species of archaea and bacteria are known.

Complete answer: TO solve this question, we have to explore more about hyperthermophilic.
-Liverworts need an extremely cold climate for growing very short, (10cm) tall by the protection of strong, powerful snow storms. They are also capable of continuing photosynthesis at very low temperature and low light.
-Yeasts can grow in the mesophilic range of temperature (25-30° C) or generally yeasts grow from (0°C to 47°C).
-Eubacteria and Archaebacteria are the organisms found in submarine hydrothermal areas which can grow at (80-100°C) or above temperature, and are not able to grow below 60°C.
-Cyanobacteria need higher temperatures than most algae. The temperature will be higher than 25°C and diatoms need lower temperatures than other algae that is (17-22°C).
-Protists generally need 20°C temperature for their better or good type of growth. Grains are suitable sources of bacteria for feeding most of the Protozoa. Mosses can survive in the temperature range from 15°C to 40°C.

So, the correct answer is option (B) Eubacteria and Archaea, that’s why hyperthermophiles belong to this family.

Note: There are various applications of hyperthermophilic:
-Extremozymes describe the enzymes that can perform functions at very high temperature and low Ph.
-Molecular chaperons are those types of proteins that express stress conditions like elevated temperatures and are involved in the folding of proteins.
