SECTION B

EXPERIMENT

1. Study of flowers adapted to pollination by different agencies (wind, insects).

2. Study of pollen germination on stigma through a permanent slide or scanning electron micrograph.

3. Study and identify stages of gamete development, i.e., T.S. testis and T.S. ovary, through permanent slides (from any mammal).

4. Study meiosis in onion bud cells or grasshopper testes through permanent slides.

5. Study of T.S. of blastula through permanent slide.

6. Study Mendelian inheritance using seeds of different colors/sizes of any plant.
