sclerenchyma cell
A plant cell with thick, lignified walls that provides structural support. Technical term used in botany.
Sclerenchyma cells give strength to plant stems and leaves.
Parenchyma tissue, composed of thin-walled living cells, contrasts with the thick-walled, often dead sclerenchyma cells.
Collenchyma tissue, with unevenly thickened primary walls, provides flexible support unlike the rigid sclerenchyma.
Compound of 厚膜 (thick membrane/wall) + 細胞 (cell), directly describing the cell's characteristic thick secondary wall.
