An example of a synarthrotic fibrous joint is

a. intervertebral discs
b. pubic symphysis
c. interosseous membrane between the radius and the ulna
d. sagittal suture

 The correct answer is :   D. sagittal suture

Explanation:    The sagittal suture connects the two parietal bones of the skull, it is a type of synartrotic fibrous joint. Fibrous joints with very little or no mobility are called synartrotic, the bones are held together by fibrous connective tissues. Synarthrosis occurs where there is bone growth. Synarthrosis protects and supports ligaments and muscles.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
