Difference Between Absorbent and Adsorbent

Difference between absorbent and adsorbent is mainly due to the following factors like their mechanism and the phenomena they follow: Mechanism: The mechanism of absorbent and absorbent is to retain the particles or molecules, in which a former absorbs the particles into the matrix, and the latter adsorbs the particles over the solid matrix. Phenomena: …

Prokaryotic Ribosomes

Prokaryotic ribosomes are dense structures, which solely contain RNA and proteins. The ribosomes in the prokaryotic cell are thoroughly distributed in the cell cytosol. There are two subunits of prokaryotic ribosomes (50-S and 30-S type). 50-S and 30-S are the large and small subunits of bacteria that colloquially constitute the 70-S type of ribosome. Here, …

Inclusions in Prokaryotes

Inclusions in prokaryotes include certain types of food reserve granules and some monolayered non-unit membrane-enclosed cytoplasmic inclusions. Cell inclusion bodies can define as the pigmented molecules, which resides within the cell. It does not function like membrane-bound organelles but performs a pivotal role to store reserve materials. Inclusion bodies occupy within the cytosol enveloped by …

Floral Formula

A floral formula is one of the ways to summarise all the flower characteristics, which makes the use of discrete letters, numbers and symbols. The letters used in the floral formula indicate the members of the perianth and other floral parts. Specific signs or symbols are also used to denote the properties like parentheses, aestivation, …

Floral Diagram

The floral diagram is a diagrammatical description of the properties like arrangement, position, structure, aestivation, connotation and adnation of the floral components. It was first introduced in the 19th century by the scientist named August Wilhelm Eichler. A floral diagram illustrates the different floral components by the characteristic symbols. It has a circular outline. There …

Nuclear Pore Complex

The nuclear pore complex encases the nuclear pore, which facilitates the translocation of macromolecules within the cell. A nuclear envelope possesses two concentric outer and inner layers fused with the NPCs. Both the phospholipid nuclear membranes are isolated by the perinuclear space in between. The nuclear membrane works as a selective barrier protecting inner nuclear …

Solenoid Model

The solenoid model illustrates the packaging or folding of DNA within the eukaryotic cell nucleus. It was first introduced by the scientist’s John Finch and Aaron Klug in the year 1976. In eukaryotes, the DNA is organized compactly due to the association of bead-like histone octamer and linker histones. Oppositely, the DNA content in prokaryotes …
