Lamellar Collenchyma Cells (Layered-Wall Cells)

Thick layers, like a stack of plates

Lamellar collenchyma cells are a kind of collenchyma: living cells that help hold up young stems.

Instead of thick corners, their thickest walls are the ones that face toward the outside and toward the middle of the stem. In a slice, these thick walls line up into stripes, like layers in a cake.

They sit in rows just under the skin of the stem. Scientists find them in plants such as elderberry stems.

A bendy, layered skin

The thick layers make a strong band all the way around a young stem, just under its skin. Like other collenchyma, the cells stay alive, so the stem can keep growing longer and still bend in the wind.

Scientists tell collenchyma types apart by where the thick walls are: in the corners, in layers, or around air spaces.
