noun
collenchyma cell
Botanical term for a living plant cell with unevenly thickened primary cell walls, providing flexible structural support.
厚角細胞は、成長中の茎や葉柄によく見られる。
Collenchyma cells are often found in growing stems and petioles.
厚壁細胞 (sclerenchyma cell) has thick, lignified secondary walls and is usually dead at maturity, whereas 厚角細胞 is living and has unevenly thickened primary walls.
Compound of 厚角 (thick-angled, referring to the uneven cell wall thickenings) and 細胞 (cell). The exact historical derivation is uncertain; the term is a modern botanical coinage.
