In the following analogy from biological terminology, FUNGI is related to MYCOLOGY as TISSUE is related to which of the following branches of study?

Introduction / Context:
This analogy is based on branches of biological science. It links a subject of study to the specialised field that studies it. Mycology is the study of fungi. The question asks for the corresponding branch of science that studies tissues in living organisms. Such analogies check both vocabulary and fundamental biology knowledge.

Given Data / Assumptions:
- First pair: FUNGI and MYCOLOGY.
- Second base term: TISSUE.
- Options: Haematology, Cytology, Histology and Bacteriology.
- We assume each option names a specific branch of biology with a standard, accepted meaning.

Concept / Approach:
Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties and their uses or hazards. The analogy pattern is object of study to academic discipline. Therefore TISSUE must be matched with the branch that specialises in tissues. Histology is defined as the study of the microscopic structure of tissues. Haematology focuses on blood, Cytology on cells, and Bacteriology on bacteria. Thus Histology is the correct parallel to Mycology in the second pair.

Step-by-Step Solution:
Step 1: Confirm the first pair. Fungi are studied under the branch called Mycology. Step 2: Interpret TISSUE as groups of similar cells performing specific functions in plants or animals, such as muscle tissue or nervous tissue. Step 3: Recall that Histology is the science devoted to studying tissues, usually under the microscope. Step 4: Compare alternatives: Haematology deals with blood and blood forming organs, Cytology with individual cells, and Bacteriology with bacteria. Step 5: Select Histology, since it uniquely corresponds to the study of tissues.

Verification / Alternative check:
Consider how each branch name is used. Histological studies always refer to tissue sections and their microscopic structure. In contrast, haematology labs analyse blood samples, cytology examines cell smears and bacteriology handles colonies of bacteria. Only Histology lines up exactly with TISSUE as the object of study, mirroring FUNGI to MYCOLOGY.

Why Other Options Are Wrong:
Haematology relates specifically to blood, not all tissues. Cytology is narrower in focusing on cells, which are the building blocks of tissues but not equivalent to them. Bacteriology is about bacteria, which are microorganisms distinct from tissues. Choosing any of these would distort the clear subject to discipline relationship that defines the analogy.

Common Pitfalls:
Students sometimes confuse Cytology and Histology because both involve microscopic work. A useful memory aid is that "cyto" refers to cells, while "histo" refers to tissues. Remembering these prefixes prevents misclassification and helps in many biology related reasoning questions.

Final Answer:
FUNGI is studied under MYCOLOGY, and in the same way TISSUE is studied under Histology.
