The shape and texture in each individual grain is made visible through the microscope. [7] As the microscopic scale covers any object that cannot be seen by the naked eye, yet is visible under a microscope, the range of objects that fall under this scale can be as small as an atom, visible underneath a transmission electron microscope. [8]
Starch grain analysis is not a perfect science, however, plant starch grain analysis is a diagnostic feature of multiple applications according to the peculiarities and to the origin of the plant material. [9] The size, shape and structure of grains from plant species, varies little, which can lead to identification.
A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy.
Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

The Feret diameter or Feret's diameter is a measure of an object's size along a specified direction. In general, it can be defined as the distance between the two parallel planes restricting the object perpendicular to that direction. It is therefore also called the caliper diameter, referring to the measurement of the object size with a caliper.
Granulometry is the measurement of the size distribution in a collection of grains. Granulometry (morphology), granulometry computation using the morphological opening operation; Optical Granulometry, computation of granulometries from images, and its use in mines; Measurement of grain sizes or particle sizes.
Particle size is a notion introduced for comparing dimensions of solid particles (), liquid particles (), or gaseous particles ().The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size).
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
