Sphagnum cuspidatum moss, and to avoid contact with the moss against scraped or cut skin. The moss prefers damp conditions, and is relatively hardy in peat bogs. It does not perform as well in completed submerged conditions as it is incapable of producing sufficient amounts of chlorophyll to grow extensively, and natural causes also result in the death of new shoots produced. Like most species of "Sphagnum", this moss has mild antiseptic capabilities. It is very absorbent and acidic, and therefore creates environments not suitable for bacterial growth. These mosses were used up until World War I to pack wounds on the
Plant cell quite elongated, and may divide transversely to give a septate appearance. The role of this cell type is to support the plant in axes still growing in length, and to confer flexibility and tensile strength on tissues. The primary wall lacks lignin that would make it tough and rigid, so this cell type provides what could be called plastic support – support that can hold a young stem or petiole into the air, but in cells that can be stretched as the cells around them elongate. Stretchable support (without elastic snap-back) is a good way to describe what collenchyma does.
