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.

Is bacillus megaterium a spore or a vegetative cell?
Bacillus megaterium is a spore-forming bacterium. It produces endospores as a survival mechanism in response to harsh environmental conditions.
The presence of a spore in a vegetative bacterial cell helps establish that the organism is of which genus?
The presence of a spore in a vegetative bacterial cell suggests that the organism belongs to the genus Bacillus or Clostridium. These genera are known for their ability to form endospores as a survival mechanism in response to harsh environmental conditions.
What are the steps to bacterial sporulation?
1. Growth stops 2. DNA is replicated 3. plasma membrane grows inward, septum forms 4. Larger cells engulf smaller cells a- larger = mother cell b-Smaller = Forespore 5. PTG laid down between two membranes>core wall and cortex 6. Mother cell produced spore coat proteins (dipicolinic acids) 7. Mother cell degrades and releases endospore.
What do you call a cell with a hard protective coat around it?
spore
Why is it necessary to perform a spore stain when you can see the presence of spores in simple stained cells?
Performing a spore stain is necessary because simple staining may show the presence of spores but does not provide enough contrast to clearly distinguish them from the rest of the cell. Spore staining uses specific dyes and techniques to highlight and differentiate spores from the surrounding cell material, providing clearer visualization and identification of spores.

What is a single cell that can grow into a new plant is called?
A plant cell that has the ability to grow into a new plant is called a meristem cell. These cells are found in the stem tips, root tips, and buds of plants and have the capacity to divide and differentiate into various specialized cell types to regenerate plant tissues and organs.
How do you get extended cell parts on spore?
well you can go to the secret cell editor by right clicking the spore icon,going to properties,and putting at the end -state:CellEditor. you can also look for a mod but that's hard!
Is a spore a cell?
yes a bacterial cell is an endo spore

In spore staining what would happen it you used safarin as the primary stain and malachite green as the counterstain?
The spore would appear to be red as the safranin is heat driven into the many layers of the spore, however, as Malachite green has a weak affinity and is water soluble, it will not likely bind to the spore wall or the cell wall. You might have traces of green on the slide if any, but it will be very little. Your vegetative cells will be pink as well.
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.

What is a spore forming group of organisms?
Spore formers are a group of bacteria which form an endospore. When certain bacteria are stressed, sub-lethally injured, or placed in danger in any way it will form what is know as an endospore. The endospore contains all of the necessary genetic information necessary to regenerate a new vegetative bacterial cell if the bacterium is killed or lethally injured. Endospores will not germinate into vegetative cells unless the original bacterium is killed and the threat has subsided.
