Which of the following are likely to be present in deep sea water?
Archaebacteria
Eubacteria
Blue-green algae
Blue-green algae
A.
Archaebacteria
Archaebacteria flourish is hot springs and deep sea hypothermal vents. Eubacteria are true bacteria, characterised 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 saprophytes. The cyanobacteria have chlorophyll-a similar to green plants and are photosynthetic autotrophs.
