A. List of Experiments
1. Study and description of three locally available common
flowering plants, one from each of the families Solanaceae,
Fabacceae and Liliaceae including dissection and display of
floral whorls, anther and ovary to show number of chambers
(floral formulae and floral diagrams). Types of root (Tap
and adventitious); stem (herbaceous and woody); leaf
(arrangement, shape, venation, simple and compound).
2. Preparation and study of T.S. of dicot and monocot roots
and stems (primary).
3. Study of osmosis by potato osmometer.
4. Study of plasmolysis in epidermal peels (e.g. Rhoeo leaves).
5. Study of distribution of stomata in the upper and lower
surface of leaves.
6. Comparative study of the rates of transpiration in the upper
and lower surface of leaves.
7. Test for the presence of sugar, starch, proteins and fats.
Detection in suitable plant and animal materials.
8. Separation of plant pigments through paper
chromatography.
9. Study of the rate of respiration in flower buds/leaf tissue
and germinating seeds.
10. Test for presence of urea in urine.
11. Test for presence of sugar in urine.
12. Test for presence of albumin in urine.
13. Test for presence of bile salts in urine.
B. Study/observation of the following (spotting)
1. Study of the parts of a compound microscope.
2. Study of the specimens/slides/models and identification
with reasons - Bacteria, Oscillatoria,Spirogyra, Rhizopus, mushroom, yeast,
liverwort, moss, fern, pine, one monocotyledonous plant,one dicotyledonous plant
and one lichen.
3. Study of virtual specimens/slides/models and identification
with reasons - Amoeba, Hydra, liverfluke, Ascaris, leech,
earthworm, prawn, silkworm, honeybee, snail, starfish,
shark, rohu, frog,lizard, pigeon and rabbit.
4. Study of tissues and diversity in shapes and sizes of plant
and animal cells (palisade cells, guard cells, parenchyma,
collenchyma, sclerenchyma, xylem, phloem, squamous
epithelium, muscle fibers and mammalian blood smear)
through temporary/permanent slides.
5. Study of mitosis in onion root tip cells and animals cells
(grasshopper) from permanent slides.
6. Study of different modifications in roots, stems and leaves.
7. Study and identification of different types of inflorescence
(cymose and racemose).
8. Study of imbibition in seeds/raisins.
9. Observation and comments on the experimental set up for
showing:
a) Anaerobic respiration
b) Phototropism
c) Effect of apical bud removal
d) Suction due to transpiration
10. Study of human skeleton and different types of joints with
the help of virtual images/models only.
11. Study of external morphology of cockroach through
virtual images/models.
