Stem Structure and Functions

The video tutorial from Raju's Natural Science Academy covers the structure and functions of the stem, a key component of the plant's shoot system. It explains the parts of the stem, including nodes, internodes, axillary buds, and terminal buds, and their roles. The tutorial includes a practical observation of these parts in a hibiscus plant. It also outlines the stem's functions, such as supporting branches, transporting water and nutrients, and storing food. The session concludes with a homework assignment to collect modified stems like potatoes and ginger, reinforcing the learning objectives.
