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 perianth and other floral parts. Specific signs or symbols are also used to denote the properties like parentheses, aestivation, adhesion …

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

Nuclear pore complex encases the nuclear pore, which facilitates translocation of macromolecules within the cell. A nuclear envelop possesses two concentric outer and inner layer that are 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 and also protects …

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 named John Finch and Aaron Klug in the year 1976. In eukaryotes, the DNA is organized compactly by the association of bead-like histone octamer and linker histone, while in prokaryotes the DNA content …

Plant Cell Nucleus

A plant cell nucleus is a specialized structure, which stores the genetic information and monitors the cellular activities. Plants are the monokaryotic cells, which possess an individual nucleus. A well-developed nucleus is only found in the advanced or multicellular organisms, those having division of labour. The number of the nucleus varies among different groups of …
