INDEX : Particulars of the Experiment Performed.
SECTION A
1. Prepare a temporary mount to observe pollen germination.
2. Study the plant population density by the quadrat method.
3. Study the plant population frequency by the quadrat method.
4. To prepare a temporary mount of onion root tip to study mitosis.
5. Isolate DNA from available plant material such as spinach, green pea seeds, papaya, etc.
SECTION B
1. Study of flowers adapted to pollination by different agencies (wind, insects, birds).
2. Study of pollen germination on stigma through a permanent slide or scanning electron micrograph.
3. Identification of stages of gamete development, i.e., T.S. testis and T.S. ovary, through permanent slides (from grasshoppers/mice).
4. To study meiosis in onion bud cells or grasshopper testes through permanent slides.
5. Study of T.S. of blastula through permanent slides (mammalian).
6. Study Mendelian inheritance using seeds of different colors/sizes of any plant.
7. To study prepared pedigree charts of any one of the genetic traits, such as rolling of the tongue, blood groups, earlobes, widow’s peak, and color blindness.
8. Exercise on controlled pollination—emasculation, tagging, and bagging.
9. To identify common disease-causing organisms like Ascaris, Entamoeba, Plasmodium, and ringworm through permanent slides, models, virtual images, or specimens. Comment on symptoms of diseases that they cause.
10. To study the symbiotic association (models/specimens) found in root nodules of leguminous plants, Cuscuta on host, and lichens.
11. To study homologous and analogous organs with the help of flashcards/models.
