What is true for archaebacteria?

  1. All halophiles
  2. All photosynthetics
  3. All fossils
  4. Oldest living beings

Answer

(4) Oldest living beings

Solution

As per NCERT, archaebacteria are special bacteria that live in some of the most harsh habitats: extreme salty areas (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens).

⇒ Not all are halophiles, and they are not photosynthetic.

∵ They are living organisms, they are not 'all fossils'.

Archaebacteria are regarded as the oldest living organisms (most primitive living beings), as their habitats resemble the conditions of the early Earth.

∴ Archaebacteria are the oldest living beings.
