Question

Which of the following classification is based on some morphological characters?
A. Artificial
B. Natural
C. Phylogenetic
D. Both A and C

Answer 1

Hint: The study of size, shape, structure of animals, plants, microorganisms and the relationship between their constituent parts is known as morphology. The term anatomy also refers to the study of biological structures, but generally refers to the study of the details of gross or microscopic structures. So basically, morphological characters include size, shape, color, etc. for an organism or plant.

Complete answer
Option A: Artificial: The artificial classification system is based on the presence or absence of a morphological or vegetative characteristic, used to group together organisms or to distinguish one group of organisms from another. Characteristics such as number and position of stamens, style, etc. was considered. Since the artificial classification system is based upon morphological characters.
So, option A is the correct answer.
Option B Natural: Natural classification or taxonomy is an ascending classification based on the grouping of similar related species and the formation of a higher unit taxonomy by grouping together similar units of lower ranks. Since it is not based on morphological characters.
So, option B is not correct.
Option C Phylogenetic: The classification of organisms based on the evolutionary history and common ancestry of the organism is called phylogenetic classification. It provides us with the underlying cause of differences in the genetic diversity of organisms. Since this classification is not based on morphological characters.
So, option C is not correct.
Option D Both A and C: Here, only option A is correct and C is not correct.
Hence option D is wrong.

Therefore, Option A. Artificial is the correct answer.

Note:
The advantage of artificial classification systems is that they are easy to develop and relatively stable. Disadvantage is that they often do not show evolutionary relationships and for this reason, they are not commonly used. It is considered the oldest classification system in which plants are classified on the basis of one or very few specially selected characteristics. An example of an artificial classification system is the Linnaeus system.
