NEETZoologyStructural Organisation in Animals
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Blood is classified as a specialized connective tissue. Reason (R): Like all other connective tissues, blood cells secrete structural protein fibres such as collagen to form a matrix. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- DBoth (A) and (R) are not correct
Correct answer
C. (A) is correct but (R) is not correct
Step-by-step solution
Assertion (A) is correct because blood, along with cartilage and bone, is classified as a specialized connective tissue. Reason (R) is incorrect because blood is the only exception among connective tissues where the cells do not secrete fibres of structural proteins (like collagen or elastin). Instead, it consists of a fluid matrix called plasma in which the cells are suspended. Therefore, (A) is correct but (R) is not correct. Answer: (A) is correct but (R) is not correct
