Question

Barophilic prokaryotes

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

Answer 1

The correct option is C Grow and multiply in very deep marine sediments.

The prokaryotic organisms are found in different places and especially in the aquatic habitats. There are prokaryotes which can live in the depths of seas and oceans. As we move to the depth of the marine habitats, there is an increase in the pressure. The prokaryotic organisms which have adapted to survive in the sediments where there is increased pressure are known as barophilic prokaryotes. They can divide, grow and colonise the sediments in the aquatic habitats.
Thus, the correct answer is option C.
