Q2 / 200 · NEET 2005 · Botany

Barophilic prokaryotes:

  • Correct answer
    A
    grow and multiply in very deep marine sediments
  • B
    occur in water containing high concentrations of barium hydroxide
  • C
    readily grow and divide in sea water enriched in any soluble salt of barium
  • D
    grow slowly in highly alkaline frozen lakes at high altitudes.

Solution

Barophilic prokaryotes grow and multiply in very deep marine sediments. A barophilic prokaryote, also generally defined as a barophile, is a type of organism which occurs and exists at high-pressure zones, like a deep-sea bacterium and archaebacteria.

Hence, the correct answer is option: 'A'.
