11208.	Question : The arrangement of ovules within the ovary is known as placentation. What does the term placenta refer to ? Draw various types of placentations in the flower as seen in T.S. and V.S.
Answer» Solution :Placenta is a soft cushion LIKE tissue. Ovules are ATTACHED to inner surface of ovary. The arrangement of ovules within the ovary is known as PLACENTATION. The placentation are of different types namely marginal, axile, parietal basal, central and free central etc. Marginal Placentation : In this type of placentation the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows as in pea. Axile Placentation : In this type of placentation, when the placenta is axial and the ovules are attached to it in a MULTILOCULAR ovary, the placentation is SAID to be axile as in china-rose, tomato and lemon. Parietal Placentation : In this type of placentation, the ovules develop on the inner wall of the ovary or on peripheral part. Ovary is one chambered but it becomes two chambered due to the formation of the false septum, eg, mustard. Free Central Placentation : In this type of placentation, when the ovules are borne on central axis and septa are absent so ovary is one chambered. e.g. Dianthus and Primose ? Basal Placentation : In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it. eg. sunflower.

11232.	Question : The aneterior pituitary gland facilatetes growth of an individual by release of the humna growth hormone (HGH) which in turn is regulated by two hormones namely growth homone releasing hormone (GHRH) and grwoth hormone inhibiting hormone (GHIH) Imbalnce of these hormones could result in gigantism, dwarfism or acromegaly. Interpret the data given below and select the appropriate statement.
Answer» 1 and 3 will lead to gigantum while 4 and 5 will show dwarlism. 3 will show gigantism, 1 will show acromegaly and 4 and 5 will show dwarlism. 2,3 and 4 will shwo normal GROWTH. 1 will show gigantism, 3 will show acromegaly and 5 will show dwarfism. Solution :Growth hormone (GH) stimulates body growth by promoting the synthesis and deposition of proteins in tissues and growth of bones and muslces. Its deflicient secretion at an EARLY stage causes dwarfism while its excessive secretion form CHILDHOOD CASUES gigantism, its oversecretion in adulthood
