In biology, a theca (pl.: thecae) is a sheath or a covering.
In biology, a theca (pl.: thecae) is a sheath or a covering. In botany, the theca is related to plant's flower anatomy. The theca of an angiosperm consists...
The theca folliculi comprise a layer of the ovarian follicles. They appear as the follicles become secondary follicles. The theca are divided into two...
