Question
_________________ is seen when an embryo develops without fertilization by a male gamete.
Parthenogenesis
Binary fission
Multiple fission
Vegetative reproduction
Parthenogenesis
Binary fission
Multiple fission
Vegetative reproduction
Hint:
Propagation method followed in seedless fruits like banana.
The correct answer is: Parthenogenesis
- Conventionally, embryo is developed after fertilization in plants and animals
- Fertilization is the fusion of a male and a female gamete to form a zygote
- Certain exceptional cases are observed in plants
- Seedless fruits or "virgin fruits" are a result of parthenogenesis
- Parthenogenesis is found in banana, pineapple, figs, cucumbers and more
- In these fruits, hormone will trigger the ovary wall to swell and form the seedless fruit
- Fertilization requires fusion of female and male gametes
- Parthenocarpy is found in plants which are seedless
- Male gamete is not required in the formation of fruit
