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

它们也有生组织，使根和茎随着植物生长而变粗。

What happens is it rips apart the cell walls of the plant starting in the meristem.

激光会从生组织开始撕裂植物细胞壁。

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

两者都是圆锥结构，过前者里有一个生组织，而后者里是电机，发光二极管和电池各一个。

As the plant grows, stem cell clusters called meristems generate new xylem cells, which form bigger pipes to suit the plant's needs.

随着植物生长，被称为生组织干细胞簇产生质部细胞，这些细胞形成更大管道以适应植物需要。

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.

如果根需要支，一个带有自己生组织根就会像外星来物一样从旧根中心伸出来。

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.

在每个茎和根尖端，被称为根尖生组织干细胞群断地产生构建身体部位所需材料。

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地方，就会有一个芽，这是一个生组织，它有可能成长为一个支，并开始产生自己茎和叶。
