Asked in Premeth past paper pool — Biology

One of the hypotheses about origin of life is that life began deep in the oceans, in underwaterhot springs. The occurrence of which of the following organisms supports the givenhypothesis?

Correct answer: D. Archaebacteria

  • A. Sycon
  • B. Green algae
  • C. Zooflagellates
  • D. Archaebacteria

Explanation

Archaebacteria are a group of microorganisms that are well-known for their ability to thrive in extreme environments, such as those found in deep ocean hydrothermal vents. This supports the hypothesis that life could have originated in such harsh conditions. In contrast, the other organisms listed-Sycon, green algae, and zooflagellates-do not specifically exhibit adaptations for surviving in these extreme environments. Green algae, for instance, require sunlight for photosynthesis and are not typically found in the dark depths of the ocean. Sycon and zooflagellates also lack the specialized adaptations necessary for life in hydrothermal vent conditions.
