Question

Branch of botany which deals with the study of internal organization of plants is
A. Physiology
B. Ecology
C. Anatomy
D. Cytology

Answer 1

There are many branches of science which deals with the functions, mechanisms, inter relationships, internal structure, cell structure, etc.

Complete answer:
If we look at options, option A is Physiology. Physiology is that branch of science which deals with the scientific study of functions and mechanisms in the living system of various organisms.
It covers topics that include organs, cells, biological compounds, and how they all interact to make life possible but, in the question, the branch of botany is asked which deals with the study of internal organization of plants due to which this option is incorrect and gets eliminated.
Moving to option B i.e., Ecology. Ecology is that branch of science which deals with the study of inter relationship between the organisms which include humans and their physical environment.
It also seeks important connections between plants and animals and the world around them but, in the question, the branch of botany is asked which deals with the study of internal organization of plants due to which this option is incorrect and gets eliminated.
Moving to option C i.e., Anatomy. It is that branch of science which deals with the study of internal organization, structure of organisms and their parts. That is what has been asked in the question due to which this option becomes the correct option.
Last option D is Cytology. It is that branch of science which deals with the study of structure and functions of the cell which is the basic unit of life but, in the question, the branch of botany is asked which deals with the study of internal organization of plants due to which this option is incorrect and gets eliminated.

Thus, the correct answer is option C i.e., Anatomy.

Note: From all the options, physiology deals with the functions and mechanisms of organism, ecology deals with study of interrelationships, cytology deals with the study of structure and functions of the cell but as per the questions asked, anatomy deals with the internal structure due to which option C is the correct one.
