Which of the following is correctly paired with its structure and function?
A) sclerenchyma-supporting cells with thick secondary walls
B) ground meristem-protective coat of woody stems and roots
C) guard cells-waterproof ring of cells surrounding the central stele in roots
D) parenchyma-supporting cells with unevenly thickened primary cell walls

Question

Quizplus · Accepted Answer

Sclerenchyma cells have thick secondary cell walls which provide mechanical support to plants.

Answer: D
 Parenchyma cells have unevenly thickened primary cell walls which make them flexible and allow them to perform various functions such as storage and photosynthesis.

Option B is incorrect because the protective coat of woody stems and roots is actually the periderm, not the ground meristem. Option C is incorrect as guard cells are found in the epidermis of leaves, not in the central stele of roots.
