Acid-fast and Gram is used to visualize the structures in a membrane.
It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>
Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.
They stain poorly with Gram stain procedure, and appears as weak Gram-positive.
Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids, and
<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>
To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.

The term geosphere is globally synonymous with "planet Earth" or "terrestrial globe".
The term geosphere refers rather to the solid parts of the Earth, and thus opposes the atmosphere, the hydrosphere, and the biosphere.
* It is made up of living things. ==> this is Biosphere
* It is mostly solid. ==> Geosphere
* It includes liquid water. ==> Hydrosphere
* It includes Earth's surface. ==> Geosphere
* It includes Earth's interior. ==> Geosphere
* It is made up of gases and airborne particles ==> Atmosphere
