ANNEXURE

Activities /experiments suggested as optional experiments to dissection:

Study of abnormal constituents of urine: albumin glucose, acetone(abnormal constituents may be added in normal sample for practical exercise).
Dissection of a flower to separate out and display its various parts (Sepals, petals, stamens and carpels) Flowers suggested: Petunia, Hibiscus, Hollyhock, Pisum or any other large sized bisexual flower.
Making of a temporary, mount of transverse/vertical section of ovary of a flower to show placentation. (Same flowers as listed in item No.2).
Dissection of water soaked ungerminated seed to show different parts.Seeds suggested. Gram, Pea, Bean, Castor or any other large-sized dicot seed.
Preparation of stained human blood film and identification of blood cells. (Precaution: The instructors to ensure that only disposable needless/ordinary needles heated over a flame are used).
Study of haemolysis, and crenation of RBCs from human blood. (Precaution: The instructors to ensure that only disposable needles/or ordinary needles heated over a flame are used.)
Study of external morphology of adult cockroach: Body regions, identification of sex giving reasons.

Section (A) on list of Biology Practical Exercises (based on the syllabus) of class XII Biology practical syllabus gets modified accordingly. It may be noted that activity No.7 (to detect the presence of sugar in urine), activity No.8 (to detect the presence of albumin in urine) in Section B and activity No.12 in Section C (study of parts of flowers) of List of Biology Practical exercises IN THE EXISTING SYLLABUS stand deleted. It may be brought to the notice of all concerned that ALL THE ABOVE MENTIONED EXERCISES NO.1 TO 7 ARE COMPULSORY FOR STUDENTS OPTING OUT OF ANIMAL DISSECTION AND ARE TO BE DONE DURING THE ACADEMIC YEAR.
