Question

13. The process of sporangium formation and endospore maturation requires 8-8 hours. What is most eey to result if the temperature of the environment was raised to 100 C about 2 hours after the process started? A. The chromosome in the endospore would likely carry mutations. B. The endospore would form more slowly and be heat resistant C. The endospore would form properly but would be unable to germinate D. The organism would be termed a hyperthermophile E. The endospore would not form properly because it is not yet heat resistant

Explanation / Answer

Ans) the endospore would not form properly because it is not yet heat resistant.

A sporangium is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Sporulation Cycle involves the following steps: The vegetative cell with replicated genetic material is seen; Chromosome is duplicated and get separated; Cells get septated into sporangium and forespore; Sporangium engulfs forespore; Sporangium synthesizes spore layers and forespore; later Cortex and outer coat are deposited, the process of endospore maturation occurs; the degradative enzymes cause the lysis of mother cell (sporangium) to release the spore.
