Question

What is the taxonomy of an apple tree?

Answer 1

Hint: Linnaeus had done his binomial nomenclature of plants and animal species based on the classification already done by Bauhin. This type of classification system helps in giving the scientific name to the individual that includes the genus and the species of plants and animals.

Complete answer:
The genus name of the Apple tree is known as Malus having various species that depend upon the color of the apple like green apple, red apple, etc, and it belongs to the Rosaceae family. The members of the genus Malus are the deciduous trees or shrubs found in the temperate zone of the Northern Hemisphere. They are mostly found in the region where the temperature is low and have a cold environmental condition.
The taxonomic classification for malaria are as follows:
Domain - Eukarya
Kingdom - Plantae
Phylum - Magnoliophyta
Class - Magnoliopsida
Order - Rosales
Family - Rosaceae
Genus - Malus
The characteristic features of the family Rosaceae are similar in almost all their members. The various members of this family are crab apples, cooking apples, eating apples, wild apples, etc. they undergo pollination whether by cross-pollination or by self-pollination and may even hybridize easily.
Linnaeus was the first to introduce the concept of species. The word species was derived from the Greek word and was said to be taken from the bible. Around 8-8.7 million species are known to date. However, out of these only 18-$20\%$ of the species were described till now.
On the basis of common characteristic features, all the living organisms are classified into different hierarchical levels. As the number of taxonomic levels lowers the number of common characteristics becomes higher while in the case of the higher taxonomic levels the common characteristics will decrease.

Note:
Apple is an edible fruit that is cultivated worldwide and originated in Central Asia. The 'Malus sieversii' is still found in its wild ancestors. They are the trees that grow in the spring season and are deciduous in nature. When grown from the seed they are found to be grown larger. The fruit size ranges from season to season.
