COMPREHENSIVE exam (CLOSED BOOK)
Total Time: 3h
Max Marks: 120 (Part A: 60 + Part B: 60) Date: 01.12.07
Note: 1. ans Part A and Part B in separate ans sheets.
2. Answer the ques. in needed format.
3. Draw diagram where ever applicable.
PART-A (Plant Physiology)
Q1. Differentiate between:
(a) Qualitative SDPs and Quantitative LDPs (3)
(b) Nastic movement and Tropism (4)
(c) 3 kinds of companion cells (6)
Q2. (a) Briefly explain different meristems that arise during post embryonic development. (5)
(b) explain the acid growth hypothesis of auxin action. (6)
Q3. (a) Capillary hypothesis does not discuss water transport in trees. discuss why? (6)
(b) Briefly explain the important predictions that emerge from pressure flow model of phloem translocation. (8)
Q4. During a pot experiment, pot A, B and C (12×8 cm size) were filled with 3 various soils collected from various site having pH 4, eight and eight respectively. In every pot 1 wheat plant was maintained. No chemical fertilizer was applied. Data analysis after harvesting of mature plants indicated that plant grown in pot B established iron deficiency, whereas no iron deficiency was obtained in plants of pot A & C. What would be the possible cause behind it? Justify. (6)
Q5. In an experiment, 2 Mustard plants (winter annuals) sown in various pots were kept at low temperature (10ºC) for various time duration followed by high temperature (36ºC) for six days. Data analysis indicated that only 1 of the mustard plant flowered and in other plant no flowering was observed. What would be the possible cause for this observation? Justify your reasoning. (6)
Q6. What is vivipary? Suggest 1 hormone that can favour occurrence of this phenomenon. discuss how? Which hormone can be used to prevent vivipary and what is the mechanism of action of this hormone? (10)
P.T.O.
PART-B (Animal Physiology)
Q1 (a) Draw a flow chart depicting the organization of vertebrate nervous system. (5)
(b) Which anatomical feature plays an important role in formation of blood brain barrier? Which part of the brain is not subject to this barrier? Why? discuss with 1 example. (6)
Q2. (a)What are the main forces involved in Glomerular filtration? Briefly discuss the role of every. (6)
(b) elaborate the main steps needed for a substance to be reabsorbed from Glomerular filtrate to plasma. Briefly discuss. (4)
Q3 (a) Briefly discuss the mechanism of action of lipid soluble hormones. (5)
(b) What is the effect of caffeine on level of intracellular cAMP? How does it act?
(5)
Q4 (a) Suggest 10 methods by which camels adapt themselves in desert conditions.(5)
(b) Briefly discuss various kinds of intestinal movements? How are they altered with diarrhea, vomiting and constipation? (5)
(c) How will the dissociation of oxyheamoglobin be affected with altitude? (Compare situation at sea level with mountains). (5)
Q5 (a) What is Atherosclerosis? How can it lead to myocardial infarction? (5)
(b) What is Respiratory distress syndrome? How can it be treated? (5)
Q6 (a) What is Cryptorchidism? Why does it lead to sterility? (3)
(b) What is the application of pap smear? (1)
