Question

The branch which deals with the study of cell structure and function is known as
A. Histology
B. Ecology
C. Morphology
D. Cytology

Answer 1

Hint: Robert Hooke was the first person to introduce the term cytology.

Complete answer: Histology is the study of the microscopic structure of a cell or a tissue.
Cytology is defined as the branch science where the structure and function of a cell are studied.
Ecology is the study of the relation between one animal to another and the physical environment that surrounds them.
Morphology is the branch of study which deals with the form, shape, and/or structure of a cell or a tissue or an organism.

Additional information: The basic differences that separate histology and cytology are as follows:
1. In cytology, only a single cell is studied but in histology, the whole block of tissue is studied.
2. The cytological study of a cell is narrow but histological study is a wide study.
3. The slide preparation of cytology is very simple but in the case of histology, it is complex.
4. Cytology deals with the cellular areas of a cell but histology deals with the architecture of the cell.
5. The cytological study of cells is cheap but histological study is expensive.

So, here the correct answer will be option D. Cytology.

Note: There are two important branches of cytology.
There are those involved with the assessment of pre-cancerous and, occasionally, cancerous, changes of the cervix (mouth of the womb) such as in cervical cancer screening, which is generally called gynecological cytology.
