    A: List of Experiments

    1: Study and description of three locally available common flowering plants, one from each of the families Solanaceae, Fabacceae & 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).

    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).

    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 fibres 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.

    Tips to score well in CBSE Class 11 Biology Practical:

    If you have scored well in Half Yearly exams then most likely you will be going to get good marks and vice versa. Your performance in Class 11 Biology Half Yearly exam will likely to affect your Class 11 Biology practical exam’s score.

    However, if you will perform exceptionally well in Class 11 Biology Practical then you will definitely get good marks.

    Here are few important tips for Biology Practical exams:

    • Revise all the topics given in CBSE Class 11 Biology practical from NCERT textbooks.

    • Thoroughly read the complete theory behind each experiment you have performed in the Biology laboratory.

    • Also, revise whatever your subject teacher had taught you in your Biology class.

    • Methodology & Principle are the frequently asked questions during viva so be prepared.

    • In case of any trouble Consult with your teacher or lab attendant.
