The cambium appears in the parenchyma outside the outermost vascular bundles. Q14. Mention anamolous feature in Boerhaavia stem? Ans: Primary Anomaly - Presence of two large central medullary vascular bundles encircled with a second ring of 6 to 14 loosely arranged vascular bundles lying in the ground tissue. Q15. Write the scientific name, family, and importance of teak wood, red sanders, and rose wood? Ans: • Scientific Name : Tectona grandis • Family : Verbenaceae • Importance : Teak's high oil content. It is used in the manufacture of outdoor furniture and boat decks, cutting boards, indoor flooring, countertops and as a veneer for indoor finishings. Red sanders: • Scientific name: Pterocarpus santalinus • Family: Fabaceae • Importance: red sandalwood is used as a flavoring in alcoholic beverages. Rose wood • Scientific name: Santalum album • Family: Santalaceous • Importance: The wood is used for worshipping the god Shiva, and it is believed that goddess Lakshmi lives in the sandalwood tree. Q16. Define embryology? Mention the eminent Indian embryologist? And: The branch of biology and medicine concerned with the study of embryos and their development. Panchanan Maheshwari is the Indian eminent embryologist. Q17. What is micrspore ? Ans: A microspore refers to the spore produced by sporophytes. It is haploid and gives rise to a male gametophyte. Q18. What is Tapetum? Ans: The tapetum is a specialized layer of nutritive cells found within the anther, of flowering plants, where it is located between the sporangenous tissue and the anther wall. Tapetum is important for the nutrition and development of pollen grains. Q19. What is Endothecium? Ans: It is the lining of the cavity of an anther. Q20. What is Megasporangium. Mention any two types? Ans: A plant structure that produces megaspores that is Cllesd as ovule. Q21. Define Nucellus, Chalaza and Micropyle? Ans: A small opening in the integuments of the ovule through which sperm are able to access the ovum while chalaza is the location where the nucellus attaches to the integuments, opposite the micropyle. The central part of an ovule, containing the embryo sac. Q22. What is embryo sac? Mention the three types of embryo sac. Ans : Female gametophyte is called Embryo sac. (i) Monosporic , (ii) Bisporic, (iii)Tetrasporic. Q23. Define Fertilisation, Double fertilisation and Triple fusion? Ans : Fertilisation : Fusion of two haploid gametes is called as Fertilisation. Double fertilisation : If the female gametophyte fuses with two male gametes it is called as double fertilisation. Triple fusion : Triple fusion is a fusion that involves a sperms nucleus and two polar nuclei. 24. What is Ruminate endosperm? Ans: Ruminate endosperm is found in the 'Annonaceae family, it is the condition in which the endosperm is dissected by in-growths of the seed coat. 25. What is Endosperm? Mention the types? Ans: Endosperm is a tissue that surrounds and nourishes the embryo in the seeds of angiosperms. It is of three types (i) Nuclear endosperm, (ii) Cellular endosperm, (iii) Helobial endosperm
