Question

3. Nolo Bait®, which contains spores of the obligate intracellular fungus Nosema locustae, has been licensed by the EPA as a control measure for grasshoppers. Nolo Bait is also called “Grasshopper Spore.” N. locustae spores and bacterial spores are similar in all of the following ways EXCEPT:

a. Both spores are used for reproduction.

b. All of the above are true of both types of spores.

c. Both spores can remain viable in the environment for long periods of time.

d. Both spores remain inert under adverse conditions.

Explanation / Answer

C both spores cannot remain viable in environment for long periods of time.

Fungal spores cannot remain viable for long periods of time bacterial spores are known as endospores they are hear resistant and are resistant to chemicals and radiation whereas fungal spores are known as exospores they are less resistant to heat ,chemical and radiation.bacterial endospores are much more efficient as when bacteria undergo harsh conditions a vegetative cell of bacterium degrades but endo spores survive.while fungal spores are exspores they undergo reproduction nwhen release d in environment.bacterial spore are prokaryotic while fungal spores are eukaryotic.we can say that bacterial spores are used for survival wherein as fungal spores are used for reproduction .All though both bacterial and fungal spores are reproductive unit.
