When we climb up a mango or a guava tree, we do so by holding on to the long straight parts of the tree. This part is the stem of the tree. If you have experienced sitting on a tree while tasting its fruit, the long extended parts you sat on are branches. Branches are also parts of the stem. The place from which branches and leaves grow is stem. It has node, inter node and buds.
(i) Node – The place from where the lanes grow is node.
(ii) Inter node – The space between two nodes is inter node. The inter node helps the plant to grow and keeps it erect. No roots, leaves or branches grow from the inter node.
(iii) Bud – The angle formed by the stem and the leaf is called axil of a leaf. Generally, buds grow in the axil. However, it may also grow at the apex of the stem. The axiliary bud grows in the axil and apical bud grows in the apical position of the stem or branch.
