Stamen


In the field of botany, the male reproductive organ belonging to flowers and which have small pollen bags called microsporangia in which pollen is produced is called stamen, this term derives from the Latin language specifically from the word “stamen” which means long wool threads, generally these structures have an extension known as filaments, which have an anther at the top.

The stamen has a series of structures which are described below, the first is the so-called quarry, which can be found in two different ways, which can be versatile since it is attached to its center thanks to a fine thread, in these cases the release of the pollen will be carried out thanks to the pores, on the other hand there is the basified type union, which is adhered to the base of the filament and therefore its name. Something that should be highlighted is that the stamen can be fused to the same whorl, for which there are three types: the sinander, where only the anthers are fused, the diadelphs, partially fused into two structures, and finally the monadelphs. , attached to a single composite structure.

The other structure that makes up the stamen is the filament, it encompasses the entire base of the stamen, it has the shape of threads located in the lower part with respect to the anther, serving as support for it. Its shape and size can be very diverse, this will depend merely on the family to which it belongs.

In flowering plants, the stamen can be of two types, laminar or filamentous, in the latter case it is called connective to a sector of sterile tissue that is located in the anther which is responsible for uniting two thecae, thus forming the body, the most frequent thing is that this structure is very poorly developed, therefore it is the theca that stand out, in some primitive species the stamen in its entirety can be of the laminar type, in this case the connective will develop widely, for what the theca will separate in great form.
