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.

Endospores themselves do not release toxins. Endospores are dormant, resistant structures produced by some bacteria to survive harsh conditions. However, when the endospore germinates and the vegetative cell grows and replicates, it can produce toxins.

In asexually reproduced cells, such as those created through binary fission in bacteria or mitosis in eukaryotic cells, the number of chromosomes remains the same as the parent cell.
Bacillus megaterium is a spore-forming bacterium. It produces endospores as a survival mechanism in response to harsh environmental conditions.
No, Staphylococcus Aureus is a gram positive facultative anaerobe. It has a cell wall surrounding a peptidoglycan layer, however does not produce an endospore like many other gram positive bacteria. Staphylococcus Aureus is a cocci shaped bacteria with pyogenic properties.
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.

it reproduces by cell division.
No. Cotton plants are reproduced through their seeds. Commercial cotton -- the fibre -- is harvested from the cotton bolls what grow on the shrub.
Endospores lay dormant until conditions are such that they can re-activate the cell.
Bacillus megaterium forms central endospores, which are located in the center of the bacterial cell. These endospores are highly resistant structures that allow the bacterium to survive in harsh conditions.
I believe that you are referring to a bacterial endospore. Only a small number of bacteria can produce these (Gram-positive Firmicutes). Endospores are very tough and allow the bacteria that can produce them to survive high temperatures, pressures, drought, etc.
