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.

Why does exposure to uv radiation cause death in vegetative cells but not endospores?
Endospores are more resistant for several reasons
Difference between endospores and vegetative cell?
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.
Assume you stain Bacillus by applying malachite green with heat and then counterstaining with safranin Through the microscope the green structures are?
The malachite green penetrates the endospores, the counterstain of safranin will stain the vegetative cells. Endospores - greenish-blue Vegetative Cells - Red/Pink
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
Where within the epiphyseal plate is the dividing cartilage cells located?
It is located in the marrow cavity
What is the purpose of the bacterial endospores laboratory exercise?
To differentiate the bacterial endospores from the vegetative cells and to identify the morphology and location of the bacterial endospores.

Is cocci assotiated with endospores?
Bacillus cells produce endospores.
Why are endospores important to the food and medical industries?
Endospores can survive in harsh elements for long periods of time. Because of their tenacity it is important in the food and medical industries that all attempts are made to destroy all endospores so that the bacteria does not contaminate the product.
Why do endospores represent a challenge to the fields of industrial and medical microbiology?
Endospores are basically indestructible and have the capacity to adapt to an environment that starts to change in a hostile way. It is resistant to most agents that are normally used to kill other vegetative cells. They can survive without nutrients, in extreme temperatures and can allow bacteria to remain dormant for centuries.
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.
Are endospores acid fast?
No, endospores are not acid fast because they are not cells. Endospores will stain with the acid fast stain and look fuchsia but they are not positive for acid fast.
What are thick walled cells of botulism?
Spores or Endospores.
Where are chloroplasts located?
Chloroplasts are located in the palisade cells of the plant. Within these cells they are found within cytoplasm.
