Question

The science of the structure of animals and plants based upon dissection and microscopic observation is known as
A. Anatomy
B. Biochemistry
C. Physiology
D. Biophysics

Answer 1

Hint: Dissection word is derived from the Latin word ‘dissecare’ which means to cut to pieces. It is used for the study of anatomical structures of animals and plants by cutting the deceased animal or plant and observing under the microscope if the dissected part is not visible to naked eyes.

Complete answer:
Anatomy is the field of science that is concerned with the identification and study of the structure of animals and plants by dissecting or to cut open them. Three broad areas in the field of anatomy are human anatomy, zootomy (animal anatomy), and phytotomy or plant anatomy.

Biochemistry is one of the branches of science that deals with the study of chemical processes taking place inside the living organism. It is a combination of biology and chemistry which makes use of chemical techniques to understand biology-related problems.
Physiology is a broad field of science that deals in studying the mechanisms of living things ranging from the cellular level to the organ system level including the behavior of the whole body and the external environment’s influence. The various subdivisions under physiology include human and plant physiology, cellular physiology, microbial and viral physiology, ecological physiology, etc.
Biophysics, as the name indicates, is composed of two fields of science i.e., biology and physics. Hence, it utilizes the physical methods to understand biological processes.

So, the correct option is (A).

Note: Anatomy can be divided into macroscopic and microscopic anatomy depending on whether the dissected part is visible to naked eyes or not, respectively. The microscopic anatomy serves the purpose of identifying and studying certain tissues or cells which are not visible to naked eyes and makes use of a microscope to make them visible.
