Question

Which of the following system of classification is based on the gross morphology of plants?
A. Natural system
B. Artificial system
C. Practical system
D. All system

Answer 1

Morphology belongs to a branch of biology which deals with the study of the structure and form of organisms and their specific structural features. Morphology is of two types: external morphology and internal morphology. Internal morphology is also called anatomy and external morphology is called eidonomy.

Complete answer: Plant morphology is also called Phyto morphology. It deals with the study of the external structure and physical form of plants. Visual identification of plants is done with the help of plant morphology. Plant morphology is used in four major areas. Morphology is used for the comparative study of different plants within the same or different species. The vegetative structures and reproductive structures are observed in plant morphology. The pattern of development is studied in plant morphology. In the natural system, the plants are classified on the basis of natural affinities and not on the character which is used for determining the affinities. In comparison with the artificial system, it is based on the proper utilization of all figures and facts available in nature. The plants are grouped into taxa and are named on the basis of the presence of characteristic features. The main demerit of artificial systems is that the classification is not based on evolutionary relationships.
So, option A is the correct option.

Note: Plant morphology is different from the plant anatomy. Plant anatomy involves the study of the internal structure of the plants. Plant anatomy is also called phytotomy. Michael Adanson was the first scientist to support the natural classification of systems and reject all artificial systems of classification.
