Question

which cells produce and secrete fibres and matrix​

Answer 1

Answer:

Polysaccharides and proteins secreted by fibroblasts combine with extra-cellular fluids to produce a viscous ground substance that, with embedded fibrous proteins, forms the extra-cellular matrix. Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers.

Answer 2

Fibroblast produces Fibres and matrix.

Explanation:  

• Polysaccharides and proteins produced by fibroblasts joined with extra-cellular fluids to give a viscous ground substance that, with embedded fibrous proteins, develops the extra-cellular matrix.

The three important types of fibers are produced by fibroblasts:

1. Collagen fibers,
2. Elastic fibers, and
3. Reticular fibers.

• In better connective tissues, the matrix macromolecules are secreted largely by cells called fibroblasts.
• Bone is in the form of "connective tissue" that found in body, and it is largely composed of "hardened hydroxyapatite"containing collagen.
