They also have lateral meristems that allow roots and stems to thicken as the plant grows.

Instead of being a cone containing a meristem it will be a cone containing a motor, a light-emitting diode and a battery.

If the root needs to branch off, a new root with its own meristem busts out from the center of the old one, Alien-style.

如果根需要分支，一个带有自己分组织的新根就会像外星来物一样从旧根的中心伸出来。

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.

在每个茎和根的尖端，被称为根尖分组织的干细胞群不断地产构建新身体位所需的材料。

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.

在每一片叶子与茎相遇的地方，就会有一个芽，这是一个新的分组织，它有可能成为一个分支，并开始产自己的茎和叶。
