A "shoot" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. Also, plant stem cells are totipotent while animal stem cells are multipotent. The term "shoots" is often confused with "stems". This boosts the rooting space’s surface area and ensures quicker growth. SO my questions are this. Functions of Stem. Even if a large section of stem breaks off, the plant will continue to produce. The key to successful recovery is to prune the plant to have more than one main stem.
