Parthenogenetic embryos in plants are those which are formed by
1 unfertilised eggs
2 sporophytic cells
3 fertilised eggs
4 male gametophyte
Explanation:
Parthenogenetic embryos in plants are those which are formed by unfertilized eggs. When a male gamete fuses with one egg cell, it become fertilized egg and form zygote. In flowering plants, pollen grain is male gametophyte and the embryo sac is the female gametophyte.

Which of the PGR6 induces parthenocarpy in tomatoes?
1 Auxin
2 Gibberellin
3 Cytokinin
4 Ethylene
Explanation:
Auxin induces parthenocarpy in tomatos, Auxin is a plant growth hormone or plant growth regulator and it is mainly produced in the growing tips of roots and shoots. Parthenocarpy is the formation of fruit without fertilization. This method produces a fruit with no seeds.

When seed germinates, while the fruit is attached to parent plant, it is called:
1 Apomixis
2 Vivipary
3 Parthenocarpy
4 Parthenogenesis
Explanation:
When seed germinates, while the fruit is attached to parent plant, it is called vivipary. This type of germination is seen is species of Rhizophora. Parthenocarpy is the formation of fruits without fertilization. Development of an embryo without fertilization is called as parthenogenesis. Apomixis is an asexual method of seed formation from ovule.

Seed coat is derived from :
1 pericarp
2 epicarp
3 integuments of ovule
4 nucellus
Explanation:
Ovule after fertilisation convert into seed and ovary convert into fruit. Seed coat is derived from integument of ovule. The outer integument of ovule develops into testa, and inner integument develop into tegmen. Pericarp is wall of fruit and is made of outer epicarp, middle mesocarp and inner endocarp. Nucellus is part of ovule that contain the embryo sac.
