Answer: 1. 8-nucleate and 7-celled

A typical (Polygonum-type) embryo sac forms from the megaspore by three mitotic divisions, giving 8 nuclei. Cell walls form around six of them: the egg apparatus (egg and 2 synergids) and 3 antipodals. The two polar nuclei lie free in the central cell.

So it is 8-nucleate and 7-celled.
