i dont know bacterial spores are the highly resistant spores.Infact the spores indicate the resting phase of some types of bacteria,which help to tide over the unfavorable conditions.These spores can also be called as endospores.These endospores contain calcium and dipicolenic acid and hence they are very much resistant.They are resistant to temperature,UV light,disinfectants etc. and thus they protect the bacterium.In the favorable conditions these develop into a new bacterium. some of the organisms that form endospores are Bacillus,Clostridium,Sporosarcina etc
Endospores are small durable cells that can withstand extreme conditions that the mother cell (vegetative cell) could not. The vegetative cell releases them when they sense chemical signals from the environment that tell them their current and possible optimum growing environment is going to change to a less habitable one. In the pursuit of carrying on life the create endospores with their genetic material. These endospores endure the harsh conditions while the vegetative cells die off and then when favorable conditions return the cell becomes vegetative again and lives to see another day. If you didn't know the vegetative cells can reproduce but the endospores can't. That is why the vegetative cells are what matter.
The bacterial endospores function is that it serves in the survival of the bacteria. An endospore is a dormant structure produced by a small number of bacteria.
To preserve a copy of nucleic acid from unfavorable environmental conditions.
Protection of genetic material during harsh conditions
Bacterial cysts differ from endospores in the way they are formed and also the degree of resistance to unfavorable conditions. Endospores are much more resistant than cysts.
Endospores enable bacteria to lie dormant for extended periods
Endospores store genetic material.
Endospores are thick-coated, resistant cells produced within a bacterial cell that has been exposed to harsh conditions. Endospores are inert and can endure extreme conditions like radiation, heat and cold, absence of nutrients and water. When conditions are good, they produce vegetative cells and thrive. When condition turn unfavorable, endospores are produced again and they remain inert. Vegetative cells are any cells of plants or animals that do not participate in reproduction. These are vulnerable to external changes and react easily. They cannot thrive in unfavorable conditions.
No.
To differentiate the bacterial endospores from the vegetative cells and to identify the morphology and location of the bacterial endospores.

If endospores are formed there can be the survival phase.
Both can survive/resist harsh conditions
Bacterial endospores can be used as indicators of sterilization efficiency because of their ability to enable bacteria to lie dormant for extended periods. If they are present then the sterilization is not efficient to kill them and thus the bacteria.
Bacterial endospores.

im actually not sure i wanted to know the same about botulism
