Answer:
Mycoplasma form colonies that resemble in shape with : (B) Fried egg.
These are spherical in their shape and resembles as filamentous cells having no walls. The attachment or the organelle is located at the filamentous tips.
They are seen in the agar and they evolve using a degenerative styled evolution. These are gram positive bacteria and closely relates to clostridia.
Answer: (B) Fried egg
Explanation:
Mycorrhiza when absorbed into the agar gel, spreads itself and cover the agar gel completely. On looking at the shape or formation of the colony of mycorrhiza, a 'fried-egg' shaped colony can be seen. This 'fried-egg' type of colony formation is the same in the case of L-forms of bacteria.
There are an estimated two reasons for the formation of such shaped colonies:
1) due to the very small dimension of minimal reproductive units
2) plasticity due to the absence of a rigid cell wall in the bacteria.
