Parthenocarpic tomato fruits can be produced by-
1 Removing androecium of flowers before pollen grains are released.
2 Treating the plants with low concentrations of gibberellic acid and auxins.
3 Raising the plants from vernalized seeds.
4 Treating the plants with phenylmercuric acetate.
Explanation:
Development of fruits without fertilization is called parthenocarpy and such fruits are called parthenocarpic fruits. - Parthenocarpic fruits are seedless. - It can be artificially induced by the application of plant hormones such as Auxin and Gibberellic Acid.

Which of the following is incorrect
1 Mango and coconut are drupe fruit
2 According to Euro norm IV sulphur content for petrol is \(50 \mathrm{ppm}\)
3 \(\mathrm{CO}_{2}\) and other poisonous gases cause pollution
4 Apple is a true fruit
Explanation:
False fruits also known as pseudo fruits or accessory fruits are not derived from the ovary of a flower, instead, they developed from other part of the flower e.g. thalamus in apple, peduncle in cashew-nut, fused perianth in mulberry and calyx in Dillenia. Jack fruit and pine apple are also false fruits as they develop from the entire inflorescence. False fruit are also called spurious or accessory fruits. - A true fruit develops from the ripened ovary (fertilized ovary). It is also knows as an accessory fruit. Mango, banana, tomato, etc. are the example of true fruit.

Seed which are able to withstand reduction in moisture and temperature are called
1 Dormant seeds
2 Recalcitrant seeds
3 Orthodox seeds
4 Non-viable seeds
Explanation:
Seeds which are able to withstand reduction in moisture and temperature are called orthodox seeds. A dormant seed is unable to germinate in a specified period of time under environmental factors that are normally suitable for germination. Recalcitrant seeds cannot stored in a conventional freezer as they cannot survive after drying or freezing at \(-20^{\circ} \mathrm{C}\). Non-viable seed fails to germinate under optimal conditions.

Parthenogenesis is a term of
1 budding
2 sexual reproduction
3 asexual reproduction
4 regeneration
Explanation:
Exp. B Development of an embryo directly from an egg without fertilisation is known as parthenogenesis. It is a term of asexual reproduction. Budding is a type of asexual reproduction, in which new organism develop part of its parent's body as a bud. Regeneration is process by which plants and some organisms restore their lost body parts. Sexual reproduction is fusion of gametes from each parent.
