*The endoplasmic reticulum is a synthesis and transport organelle that branches into the cytoplasm in the plant and the animal cell.

*The golgi apparatus is a multi compartmentalized organelle where where the synthesized molecules are packaged for delivery to the other cell components or for the secretion from the cells.

A bacterial cell that contains an outer membrane and periplasmic space stains pink to red on Gram stain. Which one of the follow
anastassius [24]

Answer:

a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.

Explanation:

Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.
