Differentiate between Parthenocarpy and Parthenogenesis. Give one example of each.

Solution

In most plants, flowers need to be pollinated and fertilized to produce fruits. However, some plants can produce fruits before fertilization or without fertilization. Parthenocarpy is the process which produces fruits from unfertilized ovules in plants. Unfertilized ovules develop into fruits prior to fertilization. These fruits do not contain seeds.

Parthenogenesis is a type of reproduction commonly shown in organisms mainly by some invertebrates and lower plants. It can be described as a process in which unfertilized ovum develops into an individual (virgin birth) without fertilization. Therefore, it can be considered as a method of asexual reproduction.

It is seen in organisms like rotifers, honeybees and even some lizards and birds (turkey). The key difference between parthenogenesis and parthenocarpy is, parthenogenesis is shown by animals and plants while pathenocarpy is shown only by plants.
