Text Solution

Verified by Experts
The correct answer is:
B

The Eubacteria are characterized by the presence of a rigid cell wall, and if motile, a flagellum. The colonies are generally surrounded by gelatinous sheath. Chemosynthetic autotrophic bacteria oxidise various inorganic substances such as nitrates, nitrites and ammonia and use the released energy for their ATP production. They play a great role in recycling nutrients like nitrogen, phosphorous, iron and sulphur.
