A gram positive bacteria will have a thick sugar-protein shell around the cell. A gram negative has a thin membrane with an outer membrane covering a thin layer of peptidoglycan around the cell.
The cell walls are the difference. Gram stain will be positive, as the cell wall is thicker. Gram-positive bacteria retain the (crystal violet) dye. Then a decolorizer will be added and then the pink counterstain. This will give all gram-negative bacteria a red or pink coloring.
All the steps are done for all cultures being Gram stained and when they grow, the color will be seen as well as the shape.
A Gram-negative bacterium has an extra layer that is outside the peptidoglycan layer of the cell wall.
The structure and composition of the cell wall is different.
Can we observe the bacteria cell structures by just using light microscope
bacteria.
No difference. Bacteria are living organisms.
Flagella are long hair-like structures and Cillia are short hair-like structures. They can both help with the movement of the bacteria and cillia could stop foreign material entering the bacteria cell.
The difference is that viruses are smaller than bacteria. One more major difference is that bacteria are living things whereas viruses are non living things.
B. Subtilus is a rod or bacilus shaped, gram positive bacteria
to eliminate gram positive bacteria from a mixture of grampositive and gram negative bacteria which procedure would be best first treatment with mild detergent or lysoyme
Heat-resistant structures in bacteria include endospores, which are dormant, tough structures that can survive extreme conditions like high temperatures. Endospores are formed by some bacteria as a defense mechanism to protect their genetic material. They allow bacteria to withstand harsh environments and continue to exist in unfavorable conditions.

what is nitrogen fixing bacteria live in these structures found in the roots of legumes
The difference between a gram positive and gram negative bacteria is the thickness/presence of the peptidoglycan layer secreted on the outside of the plasma membrane
bacteria.
The five major structures found in bacteria are capsule,ribosome,nucloid,flagella pilli,cytoplasm and pilus also
No difference. Bacteria are living organisms.
Flagella are long hair-like structures and Cillia are short hair-like structures. They can both help with the movement of the bacteria and cillia could stop foreign material entering the bacteria cell.
No, bacteria do not have microtubules. Microtubules are a component of the cytoskeleton in eukaryotic cells, providing structure and support, as well as serving as tracks for intracellular transport. Bacteria have different structural elements that fulfill similar functions, such as cytoskeletal proteins like FtsZ and MreB.
