Hypotonic Solution Definition, Examples

The capacity to an extracellular fluid that allows water to flow into or out of cells via the process of osmosis is known as tonicity.. Tonicity is a measure of its the osmolarity. A closer look at the hypotonic solution can assist in understanding this more.

Glandular Epithelium functions, definition, structure, examples

The glandular epithelium comprises a set of tissues that is not the epithelium that covers and lines that is specifically designed to secrete and produce of different macromolecules. Due to its primary role it is often referred to as"the secretory epithelium.

Stratified cuboidal epithelium

The stratified cuboidal epithelium is composed of multiple layers of cells, in which the topmost layer is composed of cuboidal cells, while the lower layer could be columnar or cuboidal. In the case of stratified squamous epithelium cells in the layers below may differ from the epithelium on top. The alteration of cells that line the apical surfaces is based on the position and purpose of the epithelial tissue. The epithelium is extremely uncommon and only occurs in a few areas of the body.

Facilitated Diffusion Definition, Principle, Examples

Facilitated diffusion is the method of biological transport where certain biomembrane structural components interact with specific solutes or classes of solutes significantly increasing the speed that they cross the membrane.

Embryological Evolution

The study of embryology, also known as embryos, is a key element of evolution in biology and can identify the commonalities and differences between different species. The embryo of an organism refers to the fertilized egg that it progresses through the stages of development, which are unique to the particular species.

Pseudostratified columnar epithelium Definition, Structure, Function, Types

A pseudostratified columnar epithelium an epithelium made up of only one layer of cells which creates the appearance of multiple layers due to the nuclei in the cells are located at various levels. It is histologically an epithelium that is simple, even though when viewed from a cross-section it could appear as an epithelium stratified. The pseudostratified epithelium composed of squamous or cuboidal cells is extremely uncommon, while the columnar epithelium that is pseudostratified occurs across the body.

Transgenic Plants Examples, Definition, Procedure, Application

The term"transgenic plants" refers to plants whose DNA has been altered by genetic engineering. This implies that the genes of another species is introduced and then merged in the genome of the plants that alters the features of the genome originally.

Binary fission Definition, Types, Steps, Examples

Binary fission can be described as a kind of sexual reproduction in which one living cell, or organelle expands twice its size, and then splits into two identical cells, which means that each of the daughter cells can be expected to grow to what size as the organelle or cell.

Phylum Arthropoda Definition, Classification, Characteristics, Examples

The Arthropods belong to the bilaterally symmetrical metamerically separated, triploblastic creatures with a coelom that is diminished and altered. Their body is externally covered in an exoskeleton made of chitin that is molts regularly as well as their appendages joined.

Phylum Hemichordata Definition, Classification, Characteristics, Examples

Hemichordata (Gr., hemi, half; chorde, cord) means they are 'half' of 'part' chordates, a fact that is disputed. They are generally vermiform single, or colonial enterocoelous coelomate species with an intra-epidermal nerve system as well as a pre-oral, with or without gill-slits, and without the typical Nephridia.
