Answer and explanation:
Gram positive bacteria :
1) They retain crystal violet stain thus staining purple
2)They only produce exotoxins.
3)Peptidoglycan is thicker and multilayered
4)Techoic acids are present in their cell walls.
5)Lipopolysaccharides are absent in their cell wall.
6)No periplasmic space present
Gram negative bacteria :
1) They retain red safaranin stain thus stain pink.
2)They produce both exotoxins as well as endotoxins.
3)Peptidoglycan is thinner and single layered.
4)Techoic acids are absent in their cell walls.
5)Lipopolysaccharides are present in their cell wall.
6)Periplasmic space in present.
A graph which represents the change in cell surface area to volume ratio with an increasing cell diameter is graph C.
<h3>The ratio of surface area to volume.</h3>
Generally, the ratio of cell surface area to volume in living organisms is always required to be very small, so as to allow sufficient materials such as food particles, to move through the cell membrane quickly for the cell's survival and optimum function.
When plotted on the cartesian coordinate, a graph which represents the change in cell surface area to volume ratio with an increasing cell diameter is shown in the image attached below.
