Question

Compared to a vegetative cell, how much less water is present in an endospore?

a) 10% less water
b) 30% less water
c) 50% less water
d) 70% less water

Answer 1

Compared to a vegetative cell, 70% less water is present in an endospore (Option D). When compared to a vegetative cell, an endospore has significantly less water content.

Step-by-step explanation:

Compared to a vegetative cell, an endospore has significantly less water content. This reduction in water content is one of the factors that contribute to the dormancy and resistance of endospores.

An endospore is a dormant structure produced by certain bacteria to withstand harsh environmental conditions.

It is highly resistant to heat, chemicals, and desiccation (drying out) due to its low water content, protective spore coat, and other unique characteristics.

For example, while a vegetative cell may have a water content of around 70-80%, an endospore can have a water content as low as 10-30%.

This reduced water content helps endospores maintain their structure and survive in unfavorable conditions for extended periods.

Hence, the correct answer is: 70% less water (Option D).
