2024 Re-NEET Structural Organisation in AnimalsConnective tissues and fibre-secreting cells Medium Question 13 of 92 in Structural Organisation in Animals

In which of the following connective tissues, the cells secrete fibres of collagen or elastin? A. Cartilage B. Bone C. Adipose tissue D. Blood E. Areolar tissue. Choose the most appropriate answer from the options given below:

A B, C, D and E only
B A, B, C and E only
C B, C and D only
D A, C and D only

The answer is B.

Solution

Cartilage, bone, adipose tissue and areolar tissue all contain cells that secrete fibres of collagen or elastin (structural proteins). Blood does not contain such fibre-secreting cells (fibroblasts); it is a fluid connective tissue without a fibrous matrix of this kind.
