The stem is the main part of the shoot that supports the plant. Although they mostly remain inactive, under favorable conditions of growth they develop into shoot, leaf or a flower, based on the requirement of a plant. Stem growth can add to the plant’s height, broaden the area covered by the leaves, or even direct growth from a dark area toward one with more light. These parts of the stem contain a lot of cells which are called ‘meristematic‘; cells which actively divide to create lots of new cells. Add to Playlist 1 playlists. c. A banana stalk bearing several bunches of bananas. Its basic constituents are the phloem and xylem vessels which form the plant’s transportation system, meristematic ‘cambium’ cells which are actively dividing cells producing more phloem and xylem tissue, and cortex cells which fill in the gaps between the other types of cells and can also store food or become meristematic (growing) in order to repair damage to the stem. In woody perennials, and some other plants, the ongoing production of phloem and xylem cells is responsible for the thickening of the plant’s stems. They may range in length from a few millimeters to hundreds of meters. 4. Lateral Bud: Small buds along length of branch that develop into leaves, lateral branches, or flowers.

The stem is the ascending part of the plant formed by the elongation of the plumule of the embryo. These buds may remain dormant or may develop into a side shoot, leaf or flower. "As we have discussed, stems hold up other plant parts that are above ground. Node: Growth region on stem.Region around bud or leaf stem. The shoot of a plant bears different parts like the stem, its branches, leaves, buds, flowers and fruits. The portfolio includes parts for Roadbikes, Mountainbikes, Gravelbikes, Crossbikes and E-Bikes. This increase in width stretches and squashes the epidermis, or ’skin’, of the stem, so the plant has to keep on producing new epidermal cells. Such buds are called leaf buds, flower buds and mixed buds, respectively. Stems can also be modified into many different forms, including. To provide mechanical support for a growing plant, stems need to be strong. Sometimes called a goose neck, a stem's design belongs to either a quill or threadless system, and each system is compatible with respective headset and fork designs: Quill: the stem inserts into the steerer tube, which is threaded and does not extend above the headset. Stem usually consist of three tissues, dermal tissue, ground tissue and vascular tissue. There is no upward stem movement from outside the valve for a non-rising stem design. These cells are larger size in the centre. The thin stalk of the leaf that connects the leaf to the node of the stem is called a petiole. Nodes can hold several leaves and buds together in a stem.
