College Entrance Examination Board Post-Office Sub-Station 84, New York, N. Y. Saturday, June 24 BOTANY 1-2.30 p. m. Answer any seven of the following questions. In this examination 37 counts will be based upon the laboratory note book, and 63 upon the following questions. I What are the organs of a typical higher (or seed) plant, and what part does each play in the life of the plant? 2 Describe the internal structure of a typical leaf, stem and root, illustrating your answer by a drawing of a cross section of each. 3 Explain the use of water in the higher plants; also how water is taken in; also how it is given off. Describe experiments illustrating the two latter subjects. 4 What are the differences, as to processes and use to the plant, between respiration and photosynthesis (food-preparation) in green. plants? 5 Describe the principal methods by which one of the following is secured by plants: (a) dissemination, (b) cross-pollination. Of what advantage is the process to the plant? 6 What processes are involved in the formation of a seed and its unfolding to a young plant? Illustrate your answer by drawings where possible. 7 Describe briefly, with illustrative drawings, the life history of some alga. 8 Describe in botanical language three plants studied by you, referring them to their proper order, genus and species. 9 What do you know as to the classification of plants into the larger groups? Indicate the relationships of these groups by some form. of diagram. 10 Select some botanical topic not included in the questions above, and write a brief exposition of it. WILLIAM F.

CHEMISTRY Tuesday, June 20 2.55-4.25 P. m. In this examination 30 counts will be based on the laboratory note book submitted by the candidate, and 70 counts on the following questions. The candidate is to answer seven questions, selecting two from each of the groups A, B and C, and one from Group D. A I Give a brief account of the discovery of any one of the chemical elements, including the name of the discoverer and the approximate date and conditions of discovery. Name three classes or kinds of chemical change, and write an equation to illustrate each. 2 Define the following terms: molecule, atom, ion, nascent state. Under what conditions is hydrogen supposed to exist (a) in the molecular state, (b) as an atom, (c) as an ion? What is allotropy, and how is it illustrated and accounted for in the case of the element oxygen? 3 Complete the following equations, using formulas: Barium chloride + sodium sulphate = Hydrogen sulphide + bismuth chloride = Sulphur dioxide + chlorine + water= Give the name and formula of (a) a binary compound, (b) an acid containing oxygen, (c) a base, (d) a normal salt. B 4 State all that takes place when steam is passed over heated iron. How may the gaseous product of the reaction be identified? Make a sketch of an apparatus which might be used to carry out this experiment. Outline an experiment to illustrate the synthesis of water, making use of the solid product of the above reaction. 5 Under what conditions is native sulphur usually found? Name two classes of sulphur compounds which occur in nature. How may sulphur dioxide be prepared (a) by an oxidizing process, (b) by reduction? Name two ways in which an aqueous solution of sulphur dioxide may be distinguished from one of hydrogen sulphide. |
