A: List of Experiments (60 Periods)
1. Study and description of three locally available common flowering plants, one from each of the families Solanaceae, Fabaceae and Liliaceae (Poaceae, Asteraceae or Brassicaceae can be
substituted in case of particular geographical location) 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).

1. Study 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, liver fluke, 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 animal cells (grasshopper) from permanent slides.

6. Study 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 setup for showing:
a) Anaerobic respiration
b) Phototropism
c) Effect of apical bud removal
d) Suction due to transpiration

10. Study the 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.

Practical Examination for Visually Impaired Students Class XI

B. List of Practicals
1. Study three locally available common flowering plants of the families – Solanaceae, Fabaceae, Liliaceae
and identify: Types of roots as Tap and Adventitious Types of stems as Herbaceous or Woody Types of leaves as Compound or Simple

2. Study the parts of a compound microscope- eyepiece and objective lens, mirror, stage, coarse and fine adjustment knobs.

3. Differentiate between monocot and dicot plants based on venation patterns.

4. Study the following parts of human skeleton (Model): Ball and socket joints of thigh and shoulder Rib cage

5. Study honey bee through the comb, snail through the shell, Starfish through the model, and Pigeon through the model.

6. Identify the given specimen of a fungus – Mushroom.

7. Study the adaptive features of xerophytic plants.

8. Study the process of osmosis through endosmosis in raisins.

9. Identify and relate the given experimental set up with aim of experiment: Paper Chromatography
 or Potato Osmometer

Practical examination pattern varies a bit subjectwise and a lot also depend upon the External invigilator ( Generally They are good and cooperative in nature) . Subjectwise here are some of the important points that can give you an edge. Do keep in mind that practical has to be dealt with you and external examiner. Both of you don’t know each other.

Now here are some tips

1. Understand concepts, don’t mug-up anything.
2. Try to do all practicals by yourself.
3. Develop an interest to keep practicing. If you love the subject, the subject will love you back.
4. Be respectful to the examiner.
5. Keep yourself tension free. You must not appear tensed in front of examiner.
6. Don’t lose your stamina. Don’t tell them that you are not afraid of him/her or anything else.
7. Remember that you have to leave an expression on him/her how bold it is.
8. Look into his/her eyes straight. 
9. Pay full attention to examiner. 
10. If you don’t know the answer, or be it hard to guess, Stay it on until he tells the correct ones.
