Question

Describe briefly about parthenogensis and parthenocarpy?

Answer 1

1.parthenocarpy:-

it is the natural or artificially induced production of fruit without fertilization of ovules, which makes the fruit seedless. Stenospermocarpy may also produce apparently seedless fruit, but the seeds are actually aborted while they are still small. Parthenocarpy (or stenospermocarpy) occasionally occurs as a mutation in nature; if it affects every flower the plant can no longer sexually reproduce but might be able to propagate by apomixis or by vegetative means.

2.Parthenogenesis :-

it is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization. In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants parthenogenesis is a component process of apomixis.

Parthenogenesis occurs naturally in some plants, some invertebrate animal species (including nematodes, water fleas, some scorpions, aphids, some mites, some bees, some Phasmida and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and very rarely birds.

Parthenogenesis:
I this type of asexual reproduction the female gametes, develops into an organisms without its fertilisation.
Parthenocarpy:
The development of fruit without prior fertilization.
