Under dry or unfavorable conditions some gram-positive bacteria will form a thick coat and the cell contains little cytoplasm, genetic material, and ribosomes. To then rest and only reappear when conditions are stable. This ability is known as ____
A
CAPSULE
B
endospora
C
flagella
D

E
ribosome
Explanation: 

Detailed explanation-1: -The spore is formed as a response to adverse conditions. Bacterial spore is a resistant structure to unfavorable environmental conditions. Each cell produces only one spore and each spore germinate to one vegetative cell. The spore is just a part of the life cycle of spore forming bacteria under unfavorable conditions.

Detailed explanation-2: -Some bacteria form resistant endospores at the onset of extremely unfavourable environmental conditions. Growth stops, tough wall forms around the dry shrunken cytoplasm, cell ruptures releasing the endospore.

Detailed explanation-3: -Give three examples of diseases caused by an endospore-forming bacterium and the name of the specific bacterial agent involved? Examples of diseases caused by an endospore-forming bacterium include Bacillus anthracis (anthrax), Clostridium tetani (tetanus), and Clostridium perfringens (food poisoning).
