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.

Where are endospores located within vegetative cells?
Endospores can form within different areas of the vegetative cell. They can be central, subterminal, or terminal. Central endospores are located within the middle of the vegetative cell. Terminal endospores are located at the end of the vegetative cell. Subterminal endospores are located between the middle and the end of the cell.
The function of bacterial endospores is?
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

What color are bacterial endospores after a gram stain is performed?
Gram-staining does not stain the endospore due to the tough, resistant water-proof structure. It appears as an unstained area in a vegetative cell. Malachite green must be forced into the endospore with heat to stain it.
What is the function of endospore in a cell?
Endospores enable bacteria to lie dormant for extended periods

Is bacillus megaterium a spore or a vegetative cell?
It is an endospore former, but it will only form endospores when the environmental conditions are harsh. Thus, it can be a vegetative cell or spore depending on environemental conditions.

When a cell produce an endospores has that cell reproduced explain?
Endospore formation has not been considered as a mode of reproduction. During adverse conditions, vegetative cells form endospore, which on the availability of favourable conditions will absorb water and germinate to form the vegetative cells again. Endosopres are thick walled structures. Under unfavourable conditions the endospore are non porous and resistant to high salt and acidic conditions which the normal vegetative cells are sensitive to. Often the vegetative cell loses the major part of its cytoplasm to form an endospore. Thus the endospore consists of only the genetic material surrounded by minimum quantity of cytoplasm.
Which process has divisions mitosis and meiosis?
There are two types of cell division-mitosismeiosisThe difference in between them is that mitosis takes place in vegetative cells while meiosis in reproductive cells.
Resistant cell that can survive harsh conditions?
endospores
What would not be found in the cytoplasm of a bacterial cell A endospores B ribosomal RNA C nucleoid D porins?
endospores
What are the properties that differentiate the spore from the vegetative cell?
In the spore stain malachite green is used as a primary stain. This is driven into the cell by heat because of the impermeability of the spore. The stain is allowed to sit for 30 mins to make sure it gets in to the endospores.The stain is then washed and counterstained with safranin red. The endospores retain the green colour from malachite green and of course appear green under the microscope. Whereas the vegetative cells will appear red.
