Clusters of stem cells, called apical meristems, at the tip of every stem and root continually produce the materials needed to build new body parts.

在每茎和根的尖端，被称为根尖组织的干细胞群不断地产构建新身体部位所需的材料。

At the point where each leaf meets the stem, there's a bud, which is a new meristem that has the potential to grow into a branch and start producing its own stem and leaves.
