collenchyma
This term is a specialized botanical descriptor used primarily in academic, scientific, and histological contexts. It describes a specific type of supportive tissue that differs from sclerenchyma in that its cells remain living at maturity, allowing the tissue to expand as the plant grows.
Because it refers to a specific type of biological tissue or cellular material, it is treated as an uncountable mass noun. It is not used to count individual cells, but rather to describe the collective tissue system within a plant's anatomy.
