- Parthenogenesis is the spontaneous development of an embryo from an unfertilised egg cell, It naturally occurs in variety of plants, where parthenogenesis usually is found in combination with apomeiosis (the omission of meiosis) and pseudogamous (with or without central cell fertilisation) endosperm formation, together known as apomixis (clonal seed production).
- Parthenocarpy is development of fruit without fertilisation.

Parthenogenesis in Sonic Plants
Parthenogenesis is a type of reproduction that occurs without fertilization in which an egg cell develops into an embryo. This phenomenon is seen in some plants and animals, including sonic plants.
Female Gamete Development into Embryo:
In sonic plants, the female gamete (egg cell) develops into an embryo without fertilization. This is a type of asexual reproduction, and the resulting offspring are genetically identical to the parent plant.
Mechanism:
The exact mechanism of parthenogenesis in sonic plants is not fully understood. However, it is thought to be related to the plant's ability to produce hormones that mimic the effects of fertilization. These hormones stimulate the development of the egg cell into an embryo.
Advantages of Parthenogenesis:
Parthenogenesis has several advantages for plants. It allows them to reproduce quickly and efficiently without the need for a mate. This can be particularly useful in environments where resources are limited or where there are few potential mates.
Disadvantages of Parthenogenesis:
However, parthenogenesis can also have some disadvantages. Since the offspring are genetically identical to the parent plant, there is no genetic diversity. This can make the plant more vulnerable to disease and environmental changes.
Conclusion:
In conclusion, parthenogenesis is a type of reproduction that occurs without fertilization in sonic plants. It allows them to reproduce quickly and efficiently, but can also have some disadvantages in terms of genetic diversity.
