With a neat labelled diagram describe the parts of a typical angiosperm ovule .

Explanation

The main part of the ovule is the nucellus which is enclosed by two integuments, leaving an opening called as micropyle. The ovule is attached to the ovary wall by a stalk, called funiculus. The basal part is Chalaza.
The embryo sac contains seven cells and the eighth nuclei located within the nucellus. Three cells at the micropylar end form the egg s ac apparatus and the three cells at the chalaza Integuments end are the antipodal cells. The remaining two nuclei are called polar nuclei found in the centre. In the egg apparatus one is the egg cell (female gamete) and the remaining two cells are the synergids.
