Female gametophyte like pollens are found in: Sorgham Vinca Hyacinthus None of these 9. Self - pollination means Transfer of pollen from one flowers to another on the different plant Occurrence of male and female sex organ in the same flowers Germination of the pollen Transfer of pollen from anthers to stigma in the same flowers 10. A close relation between a flower and a pollinating agent is best exemplified by Salvia Yucca Cocos Avena11. The interior end of pollen tube burst by the process of ............ in embryosac Enzymatic action Endo- osmosis Exo- osmosis Imbibition 12. The main embryo is developed as a result of Triple fusion Double fertilisation Syngamy Fusion of two polar nuclei of an embryosac13. When a Diploid female plant is crossed with a tetraploid male plant , the endosperm will be : Triploid Tetraploid Diploid Pentaploid 14. Embryogeny in capsella was first of all studied by Famintzin Souges Hanstein All of the above 15. Haploid, Diploid and triploid conditions respectively can be traced in : Egg, Nucellus , Endosperm Antipodal , Egg , endosperm Antipodal, synergids , integuments Endosperm, Nucellus, synergids 16. In Angiosperms, if haploid number of Chromosomes is 12 then what will be the no. Of Chromosomes in integuments and synergids 12, 12 24, 24 24 ,12 12, 2417. What cause of long dormancy in seeds Impermeable seed coat Undeveloped embryo Presence of ABA/ Ferulic acid All of the above 18. The first requirement for germination of seed is Light Water Low temperature Mineral salts 19. The viability of seeds can be ascertained with the help of IAA A.B.A. T.T.C N.A.D.P. 20. Seeds of gram are : Exalbuminous and hypogeal Exalbuminous and epigeal Aluminous and Hypogeal Albuminous and epigeal 21. Embryo of sunflower has: One cotyledon Two cotyledons Eight cotyledons Cotyledons absent 22. Which one breaks the dormancy of potato tuber Gebberellin ABA IAA Zeatin 23. The aleurone layer in maize grain is specially rich in Proteins Lipids Auxins Starch 24. Monothecous anther is found in which family Asteraceae Malvaceae Brassicaceae Liliaceae 25. Seed dormancy is due to the presence of IAA Ethylene Abscisic acid Starch 26. Nucellus is found in Cell Ovule Pollen Leaf 27. What is pollen grain Male gamete Microspore mother cell Male gametophyte Partially developed embryo 28. Pollen grains are able to withstand extremes of temperature and dedication because their exine is composed of: Suberin Callose Cutin Sporopollenin 29. In which of the following fruits is the edible part of the aril ? Pomegranate Litchi Custard apple Orange 30. The arrangement of the nuclei in a normal embryosac in the dicot plants is ? 2+4+2 2+3+3 3+2+3 3+3+2 1Utkarsh Gupta likes this.
