Editing Integument (section)

== Botanical usage ==
In [[botany]], the term "integument" may be used as it is in zoology, referring to the covering of an organ. When the context indicates nothing to the contrary, the word commonly refers to an envelope covering the nucellus of the [[Ovule#Integuments, chivai and chalaza|ovule]]. The integument may consist of one layer (unitegmic) or two layers (bitegmic), each of which consisting of two or more layers of cells. The integument is perforated by a pore, the micropyle, through which the pollen tube can enter. It may develop into the testa, or [[seed]] coat.
