Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by
Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.  

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.

Turgor pressure is a force within the cell that pushes the plasma mebrane and the cell wall in plant cells. It is also called hy
goldenfox [79]

Answer:

The relationship is that the greater the volume of water in the central vacuole, the greater the turgor pressure, due the more or less amount of water stored in the central vacuole.

Explanation:

As a consequence of the presence of a plant cell in a hypotonic extracellular medium, water passes through osmosis inside the cell, through the semipermeable cell membrane.

The central vacuole is a structure present in plant cells, whose main function is the storage of water. The amount of water present within the vacuole can cause this structure to grow larger or contract, which determines the turgor pressure, which is a phenomenon dependent on osmosis and hydrostatic pressure.

A central vacuole dilated by excess of water produces cell dilation which promotes increased turgor pressure and pushes the plasma membrane against the cell wall.
