Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Among the basic tissues of the body, only the connective tissue is found in the form of fluid, gel, flexible hard and inflexible hard forms.

Reason R: The connective tissue constitutes the maximum volume of the body and exists in the form of blood tissue, adipose tissue, cartilages and bones.

In light of the above statements, choose the correct answer from the options given below.

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true but R is NOT the correct explanation of A.
• C. A is true but R is false.
• D. A is false but R is true.

Hint:

For Assertion--Reason questions, verify three things in order: whether the Assertion is true, whether the Reason is true, and whether the Reason actually explains the Assertion. Connective tissue is the only basic tissue occurring as blood, adipose tissue, cartilage, and bone.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Connective tissue is one of the four basic tissues of the human body.
It is unique because it occurs in a wide variety of physical forms, including fluid, gel-like, flexible hard, and rigid hard tissues.
The question asks whether the Assertion and Reason are individually true and whether the Reason correctly explains the Assertion.
Detailed Explanation:
Assertion A:
The assertion is correct because connective tissue occurs in multiple forms depending on the nature of its extracellular matrix.
- Fluid connective tissue: Blood and lymph.
- Gel-like connective tissue: Areolar and adipose tissues.
- Flexible hard connective tissue: Cartilage.
- Inflexible hard connective tissue: Bone.
Thus, connective tissue is the only basic tissue that exists in such diverse structural forms.
Reason R:
The reason is also correct.
Connective tissue is the most abundant and widely distributed tissue in the human body.
It occupies the maximum body volume and includes several specialized tissues such as blood, adipose tissue, cartilage, and bone.
These examples directly illustrate the different physical forms mentioned in the Assertion.

Step 2: Relationship between Assertion and Reason:
The Reason provides the biological basis for the Assertion by identifying the major forms of connective tissue.
Since blood, adipose tissue, cartilage, and bone represent fluid, gel-like, flexible hard, and inflexible hard forms respectively, the Reason correctly explains why connective tissue is unique among the basic tissues.

Step 3: Final Answer:
Both Assertion A and Reason R are true, and Reason R is the correct explanation of Assertion A.
\[ \boxed{(A) Both A and R are true and R is the correct explanation of A. \]
