3.
Study of the characteristics of Spirogyra,
Agaricus, Moss, Fern,Pinus(either with male
or female cone) and an Angiospermic
plant. Draw and give two identifying features of
the groups they belong to
4.
Observe the given pictures/charts/models
of earthworm, cockroach, bony fish and bird. For each organism, draw their
picture and record:a) one specific feature of its phylum. b) one adaptive
feature with reference to its habitat
5.
Study of the external features of
root, stem, leaf and flower of monocot and dicot plants

Stomata
Stomata are small pores on the lower surface of leaves. They are important organs for exchange of gases. The guard cells cover these pores and open and close stomata. This slide was prepared in the laboratory with simple staining of saffranin observed under low power of microscope. It was amazing to see these inner structures.
