Leaf cell

from Wikipedia, the free encyclopedia

As leaf vane are among mosses large cells called at the corners of the sheet substrate. They occur in a few acrocarpic ( e.g. Dicranaceae ) and many pleurocarpic deciduous mosses. They are uncolored in young leaves. Their shape ranges from large, thick-walled and reddish-brown to puffed, thin-walled and translucent. Representatives of the Amblystegiaceae and the tropical Sematophyllaceae have particularly large leaf wing cells.

In addition to water storage, their function is to absorb water into the leaf, which rises capillary along the outside of the stem.
