bacterial structures which could survive unfavorable conditions are called?
Spores
Flagella
Cysts
Granuless
My answer: spores?
Spores form part of the life cycles of many plants, algae, fungi and protozoa. In bacteria, spores are not part of a sexual cycle but are resistant structures used for survival under unfavourable conditions. --Wikipedia
Yes, your answer is correct. Bacterial structures that are capable of surviving unfavorable conditions are called spores.
To arrive at this answer, we can look at each option and determine the correct one based on their characteristics and functions:
1. Spores: Bacterial spores are a dormant and highly resistant form that bacteria can form when they encounter unfavorable conditions such as nutrient deprivation or exposure to extreme temperatures, chemicals, or radiation. Spores have a thick protective coat that allows them to survive for long periods until conditions become favorable again, at which point they can germinate into active bacterial cells.
2. Flagella: Flagella are long, whip-like appendages that some bacteria use for locomotion or movement. They are not directly related to the survival of bacteria in unfavorable conditions.
3. Cysts: Bacterial cysts are another form of survival structure, similar to spores. Cysts form when bacteria encapsulate themselves within a protective membrane or envelope to withstand harsh conditions, such as desiccation or exposure to toxins. However, cysts are more commonly associated with certain protozoa rather than bacteria.
4. Granules: Bacterial granules, also known as inclusion bodies, are accumulations of various substances within bacterial cells. Granules serve storage functions for molecules like glycogen, polyphosphate, or lipids, but they are not specifically designed for survival in unfavorable conditions.
Therefore, based on the given options, the correct answer is spores.
