INSTRUCTIONS funsZ'k1. Immediately fill in the particulars on this page of the

Test Booklet with Blue/Black Ball Point Pen.2. The OMR Sheet is kept inside the Test Booklet. When

you are directed to open the Test Booklet, take outthe OMR Sheet and fill in the particulars carefully.

3. The test is of 3.00 hours duration.4. The Test Booklet consists of 180 questions. The

maximum marks are 720.5. There are three sections in the question paper A,

B, C consisting of Physics, Chemistry , Botany &Zoology having 45 questions in each section ofequal weightage. Each question is allotted 4 (four)marks for correct response.

6. Candidates will be awarded marks as stated above ininstruction 5 for correct response of each question.1/4 (one forth) marks will be deducted for indicatingincorrect response of each question. No deductionfrom the total score will be made if no response isindicated for an item in the OMR sheet.

7. There is only one correct response for each question.Filling up more than one response in each questionwill be treated as wrong response and marks forwrong response will be deducted accordingly as perinstruction 6 above.

8. Use Blue/Black Ball Point Pen only for writingparticulars/marking responses on OMR Sheet.

9. No candidate is allowed to carry any textual material,

printed or written bits of papers, pager, mobile phone,

any electronic device etc. inside the examination room.

10. Rough work is to be done on the space provided forthis purpose in the Test Booklet only.

11. On completion of the test, the candidate must handover the OMR Sheet to the Invigilator on duty in theRoom. However, the candidates are allowed to takeaway this Test Booklet with them.

107. The first few leaves after the cotyledons in theseedling of Acacia are pinnately compound but thepetioles of the upper compound leaves are flattenedand they bear few pinnae. The adult plant has onlyparallel veined leaf like flattened petioles but withoutany pinnae. These observation lead us to theconclusion that :(1) The leaves in the adult plant are reduced to

phyllode while the seedling leaves are unreduced(2) The green parallel veined structures in the adult

plant are phylloclades(3) The plant exhibits heterophylly; bearing simple

leaves in the adult plant and compound leavesin the seedling

(4) The adult plant leaves are a case of reversionwhere they become simple like cotyledons
