Just like you have veins, arteries, and capillaries, plants have several different tissue types that make up their vascular bundles. Nodes are enlarged areas spaced along the stem of a grass plant. ADVERTISEMENTS: The following points highlight the seven main organs of flowering plants. The main difference between node and internode is that the node is the point of attachment of leaves to the stem whereas the internode is the distance between two consecutive nodes. A node is a very small growth zone. Most leaves are flat and contain chloroplasts; their main function is to convert energy from sunlight into chemical energy (food) through photosynthesis. Internodes are easily visible on a plant. In the whip and tongue graft, for example, careful cuts need to be made along the grain of the wood in the internode space. But the internodes expand and look like tall plants when treated with gibberellin. M    Leaves 4. Learn tips for creating your most beautiful (and bountiful) garden ever. Flowers 6.

For example, the dwarf pea plants have expanded leaves and short internodes. Stems are usually above ground, although the stems of some plants, such as the potato, also grow underground. Prickle: a sharpened extension of the stem's outer layers, e.g. It is important to regularly trim and prune plants to keep the nodes Node: Part of the stem from where the leaves arise is called a node. Stems may be herbaceous (soft) or woody in nature. Node: a point of attachment of a leaf or a twig on the stem in seed plants. The stem bears vegetative buds which could be terminal (apical bud) for the plant to grow upwards or axillary (bud in the axil of the leaf) which give rise to lateral branches. This process has evolved multiple times within the legumes, as well as in other species found within the Rosid clade. node - the part of the stem of a plant from which a leaf, branch, or aerial root grows; each plant has many nodes. node - the part of the stem of a plant from which a leaf, branch, or aerial root grows; each plant has many nodes.
