All the ovules in an ovary are fertilized or not? If not, then all the seeds produced in a fruit will be viable or not?

Dear student,

All ovules in an ovary are not fertilised. Sometimes normal, unfertilized ovules are apparently by passed by pollen tubes and sometimes there may be sterile ovules lacking an embryo sac.

There could be seeds that are not viable. However appearances of ovules in developing and mature fruits could be deceptive. What are often inferred to be aborted seeds, in many cases, may not be seeds at all. They may be enlarged, unfertilized ovules.
