List of Experiments

1. Study pollen germination on a slide.

2. Collect and study soil from at least two different sites and study them for

  texture, moisture content, pH and water holding capacity. Correlate with the kinds

  of plants found  in them.

3. Collect water from two different water bodies around you and study them for  

    pH, clarity and presence of any living organisms.

4. Study the presence of suspended particulate matter in air at two widely different sites.

5. Study of plant population density by quadrat method.

6. Study of plant population frequency by quadrat method.

7. Prepare a temporary mount of onion root tip to study mitosis.

8. Study the effect of different temperatures and three  different  pH on the activity

   of salivary amylase on starch.      

9. Isolation of DNA from available plant material such as spinach, green pea seeds, papaya, etc.

B. Study/observation of the following (Spotting)

1. Flowers adapted to pollination by different agencies (wind, insect, bird).

2. Pollen germination on stigma through a permanent slide.

3. Identification of stages of gamete development, i.e., T.S. of testis and T.S. of ovary through permanent  slides (from grasshopper/mice).

4. Meiosis in onion bud cell or grasshopper testis through  permanent slides.

5. T.S. of blastula through permanent slides.

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

7. Prepared pedigree charts of any one of the genetic traits  such as rolling of tongue, blood groups, ear lobes, widow's  peak and colour blindness.

8. Controlled pollination - emasculation, tagging and bagging.

9. Common disease causing organisms like Ascaris, Entamoeba, Plasmodium,  

   Roundworm through permanent slides or specimens. Comment on symptoms of  

  disease that  they cause.

10. Two plants and two animals (models/virtual images) found in xeric conditions.

    Comment upon their morphological adaptations.

11. Two plants and two animals (models/virtual images) found in aquatic   

    conditions. Comment on their morphological adaptations.
