Match each supporting structure or skeletal component listed on the left with its correct structural or physiological feature on the right.
- Collenchyma tissueProvides flexible mechanical support in young growing shoots via unevenly thickened cellulose walls
- Sclerenchyma tissueProvides rigid mechanical strength in non-growing regions via dead cells with heavily lignified walls
- Thoracic vertebraePossesses long neural spines and costal facets for rib articulation in the mammalian axial skeleton
- Lumbar vertebraePossesses large, massive centra to bear body weight and support powerful back muscles
Cevap
Collenchyma matches with flexible support via uneven cellulose walls; Sclerenchyma matches with rigid support via lignified walls; Thoracic vertebrae match with long neural spines and costal facets for ribs; Lumbar vertebrae match with massive centra for weight-bearing.
Collenchyma tissue provides flexible support to active growth zones through unevenly thickened cellulose walls. Sclerenchyma tissue provides rigid structural defense and support through dead, heavily lignified cell walls. Thoracic vertebrae possess prominent neural spines and specialized costal facets for articulating with ribs. Lumbar vertebrae feature massive centra designed to sustain abdominal weight and trunk stress.
