more info :
Each ovule develops inside the ovary and
is attached to the placenta by a small stalk
called funiculus. The place of attachment of
funiculus with the main body of ovule, is called
hilum. In angiosperms, the most common type
of ovule is anatropous in which micropyle is
directed downwards and is present adjacent to
the funiculus (funicle). The ovule consists of
central parenchymatous tissue, the nucellus
which is surrounded usually by two protective
coverings called integuments viz. Outer and
an inner integument.
A narrow opening at the apex of the ovule
is called micropyle. Chalaza is the base of
ovule directly opposite to micropyle. Embryo
sac (female gametophyte) is oval multicellular
structure embedded in the nucellus.
