The phenomenon observed in some plants where in parts of the sexual apparatus is used for forming embryous without fertilisation is called
(A) Parthenocarpy
(B) Apomixis
(C) Vegetative propagation
(D) Sexual reproduction

A

Parthenocarpy

B

Apomixis

C

Vegetative propagation

D

Sexual reproduction

Text Solution

Verified by Experts

The correct Answer is:
B

Apomixis is a method to produce seeds without fertilisation. This embryo resembles mother plant genetically.
Other options are not proper because partheno carpic fruit development and apomixis both are different methods. The development of fruit without fertilisation is called parthenocarpic therefore its fruits are seedless. e.g. Banana, Grapes
(i) Vegetative propagation is a sexual type of reproduction in plants in which new organisms are production of seed or without production of ovules.(ii) In sexual reproduction from different plants of same species or opposite species, male and female gametes are produced. These gametes are connected by syngamy and forms a zygote and new organism is produced by development
