Multipotent stem cells, found in adults or in babies' umbilical cords, have a more limited capacity. Their development is limited to the cells that make up the organ system thatSome plants have cells that are able to convert from a structured, or differentiated, state to a totipotent state. One example is the ZZ plant (Zamioculcas zamiifolia). This plant is so cellularly precocious that a mere piece of leaf or stem can be used to grow a new plant. Other plants and trees can produce spontaneous buds on the stem or trunk.Often mistakenly called, bulbs, a corm is a solid underground stem, vertically oriented where tupically only one bud germinates at the end of dormancy. Stolons: These are like rhizomes inthat they are oriented horizontally. However, they are adapted to generate new plants that are clones of the original.A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.

It holds leaves in position and helps them to spread out as the stem and its branches grow. This ensures that they get enough light for photosynthesis.The biggest reason for pinching plants is to force the plant into a fuller form. By pinching back, you force the plant to grow twice as many stems, which results in a fuller plant. For plants like herbs, pinching back can help the plant to produce more of their desirable leaves. Another reason for pinching plants is to keep a plant compact.Dicot stems have their vascular bundles in a ring arrangement. Monocot stems have most of their vascular bundles near the outside edge of the stem. The bundles are surrounded by large parenchyma in the cortex region. There is no pith region in monocots. Dicot stems have bundles in a ring surrounding parenchyma cells in a pith region.The pseudo-stem is a part of the banana plant that looks like a trunk, which consists of a soft central core and tightly wrapped up to 25 leaf sheaths.
