Question

Banana is a parthenocarpic fruit, whereas oranges show polyembryony. How  are they different  from each other in respect to seeds ?

Answer 1

The banana is a parthenocarpic fruit as it develops without fertilization, whereas in oranges, additional embryos develop directly from diploid cells other than the egg, like nucellus and integument. In banana, the ovary may develop into the fruit without fertilization. The parthenocarpic fruits never contain seeds.
