Plant Biology and Classification

In this concept of species, the species is recognised by its essential characters expressed in morphology.

This method of taxonomy involves clustering of individuals of a taxon or several taxa.

In this principle of nomenclature method, a taxon must have only one correct name.

The desired size of the clusters or groupings is called the operational taxonomic unit.

This method of taxonomy refers to the use of information about small molecules produced by the action of enzymes.

In this principle of nomenclature method, names referring to two separate taxa of the same nomenclatural level are spelt with the same spellings.

It includes variety of organisms occurring in a particular habitat.

Organism shares it genus name with the closely related other organisms.

Binomial nomenclature is the formal system of naming species of living things by giving each a name composed of two parts, providing a standardized scientific name.

Gymnosperms are seed-producing plants (phanerogams) that do not produce flowers or fruits; therefore, their seeds are not enclosed in an ovary.

Whittaker's five-kingdom classification system consists of Monera, Protista, Fungi, Plantae, and Animalia.

Nostoc is a genus of cyanobacteria that forms symbiotic relationships with various plants. It is found in the coralloid roots of Cycas, the thallus of the liverwort Anthoceros, and the stems of Gunnera (misspelled as gunnena).

The inflorescence of a coconut palm is a spadix, which is a spike with a fleshy axis enclosed by a large bract called a spathe. Because it is branched, it is specifically classified as a compound spadix.

Acetabularia is a large, single-celled green alga with a shape resembling a wine glass, which is why it is commonly referred to as the Mermaid's Wine Glass.
