Which description matches sclerenchyma?

Which description matches sclerenchyma?

• A. Flexible support; can bend
• B. Rigid, strong support; thick cell walls
• C. Storage and photosynthesis
• D. Surrounds xylem

Answer: (B)

Sclerenchyma provides rigid, long-lasting support because its cells have thick, lignified secondary walls. This lignification makes the walls very stiff and strong, so the cells resist compression and growth, often remaining alive only long enough to form the supportive framework. In mature plant parts like stems and woody tissues, these cells (fibers and sclereids) act as rigid scaffolds that maintain structure. That combination of rigidity and thick walls is what this description captures. Flexible support comes from collenchyma, which has unevenly thickened, more pliable walls. Storage and photosynthesis are typical functions of parenchyma tissue. Surrounding xylem isn’t the defining trait of sclerenchyma, even though sclerenchyma fibers can be located near vascular bundles.
