Question

Morphology is the science that deals with study of-
a) Structure, size, various parts of organisms.
b) Functioning of various body organs.
c) Maintenance of temperature in the body of the organism.
d) Study or organ system in the body.

Answer 1

Hint: Morphology is the science which studies external features like skin color, appearance and other visible parts of the organism. Morphology in biology is a study of the dimensions, shapes and structure and relationships of animals, plants and other microorganisms. The term morphology refers to the arrangement of the parts of a plant or animal.

Complete answer:
Option a) structure, size, various parts of organisms: Morpho-means external or outer and logy- means study. So, the study of external and morphological characters in biological terms. This part of science deals with structure, size, appearance and structural features of any organism. Also, the internal parts like bones and organs. This is in contrast to physiology. Anatomy is an organism structure branch of morphology. There are different types of morphology such as molecular morphology, gross morphology etc.
So, option A is the correct answer.
Option b) functioning of various body organs: Functioning of various body organs comes under the category of internal characters where organs performing well or not are defined here. Be it any organism the organs should perform well for the life on-going. As mammals have complex structures and to maintain the functions it is essential for the body organs to work in a proper manner.
So, option B is not correct.
Option c) maintenance of temperature in the body of an organism: Body temperature is not at all related to morphology in any way as it means external visible features and body temperature is the thermo adaptation of any animal or organism. Maintaining the temperature of any organism is known as thermoregulation.
So, option C is not correct.
Option d) study or organ system of body- study of organs or organs system is termed as organography where this part of science deals with the organs and tissues of any new mutation or its related information.
Hence, option D is not correct.

Therefore, Option A is the correct answer.

Note:
As we discussed what morphology means and its core role is to show any visible signs of diseases or changes which animals go through in time. It can also help in research purposes like- identifying new characteristics which can be helpful and holds a mode of attraction in the field of science and research. It is also having a great importance in the field of genetics known as phenotypic characters.
