Show Answer

Answer:

Correct Answer: A

Solution:

  • Archaebacteria flourish in hot springs and deep sea hypothermal vents. Eubacteria are true bacteria, characterized by the presence or rigid cell wall and if motile a flagellum. Most fungi are heterotrophic and absorb soluble organic matter from dead substrates and hence are called saprophyte. The cyan bacteria have chlorophyll-a similar to green plants and are photosynthetic autotrophy.
