Question

Question 1(xiii)Deepali tried to match the kind of supporting tissues in plants with their characteristic features.She tabulated the pairs as follows:Supporting tissueCellular structurePDead cells, have thick walls due to deposition of ligninQElongated cells, cell wall is thickened at the cornersIdentify P and QP — Collenchyma, Q — SclerenchymaP — Sclerenchyma, Q — CollenchymaP — Parenchyma, Q — SclerenchymaP — Collenchyma, Q — Parenchyma

Accepted Answer

P — Sclerenchyma, Q — CollenchymaReason — Sclerenchyma is made of dead cells. Cell walls are thickened with lignin, making them rigid and supportive. Collenchyma is made of living cells and are elongated. Cell walls are unevenly thickened at the corners, providing flexible support.

Supporting tissue	Cellular structure
P	Dead cells, have thick walls due to deposition of lignin
Q	Elongated cells, cell wall is thickened at the corners
