An angiosperm ovule consists of the following parts:

• The ovule is attached to placenta by means of a stalk called funicle or funiculus.
• The point of attachment of funiculus to the body of ovule is called hilum.
• The main body of ovule is made of parenchymatous tissue called nucellus.
• Nucellus is covered on its outside by one or two coverings called integuments and hence ovule is rightly called as integument megasporangium.
• The integuments cover entire nucellus except for a small pore at upper end, which is called the micropyle. Micropyle is formed generally by inner integument or by both integuments.
• The place of junction of integuments and nucellus is called chalaza.
• In inverted ovules (most common type), the stalk or funiculus is attached to the main body of ovule for some distance to form a ridge like structure, called- raphe.
• In the nucellus of ovule, a large oval cell is present at micropylar end, which is known as embryo sac (female gametophyte), which develops from the megaspore.
