Question

How does lamellate collenchyma differ from lacunate collenchyma?

Answer 1

Lamellar Collenchyma
In this type, the deposition of hemicellulose and pectin occurs only at the crosswalls separating the adjacent cells. The cells are compactly arranged without any intercellular spaces. This type is found usually in the petiole of leaves. Whereas in Lacunar Collenchyma
the cells are either spherical or oval in shape and enclose small intercellular spaces. The deposition of hemicellulose and pectin occurs only along the border of intercellular spaces. This type of collenchyma is usually found in the fruit wall.
