    Class IX

    BIOLOGY

    Students studying in class IX have to prepare Biology practical file based on following experiments:

    1. To Test the presence of starch in a given food sample .

    2. To test the presence of the adulterant matanil yellow in dal.

    3. To prepare a stained temporary mount of onion Peel.

    4. To identify parenchyma and sclerenchyma tissues in plants, striped muscle fibers and nerve cells

    in animals from prepared slide and to draw their labeled diagrams.
