Question

During a microbial study ,a spore was observed surrounded by different layers.These can withstand temperature as high as ${100}^{o}C$ or as low as ${100}^{o}C$ ,so they can remain unharmed during pasteurisation. From these characters spore must be:-

• A. Ascopores
• B. Endospore
• C. Auxospore
• D. Basidio spores

Answer 1

The correct option is B Endospore

Ascospores are sexual spores produced in ascomycetes and are arranged in fruiting bodies called ascocarps.

Endospores are tough layered structure produced by bacteria to withstand adverse conditions.

Auxospores are produced in diatoms to restore normal size.

Basidiospores are produced in basidiomycetes and are arranged in fruiting bodies.

So the correct option is 'endospores'
