Suggested Transactional Processes Providing opportunities to observe various kinds of plants and categorising them as herbs, shrubs and trees. Drawing pictures of leaves and colouring them. Showing through simple experiments different functions of the leaf (showing stomata, green pigment) to explain transpiration, photosynthesis (in simple language using non-scientifi c terms).

Key Concepts Parts of plants and their uses (Revisiting earlier concepts). Roots: kinds of roots, their functions Shoots: functions of the stem. Functions of the leaf: Photosynthesis, transpiration process (in simple Iodine test for starch in leaves. Products obtained from plants such as food items, wood, coir, rubber, fi bres.
