Not an herb and not a tree, shrubs' in-between status carries ecological advantages allowing them to grow almost everywhere. Many are fire-adapted, some communicate through volatile organic compounds released by the leaves, and others exude chemicals from their roots that prevent other plants from growing nearby.

Learn how the pressure flow hypothesis models the movement of sugars through the plant's phloem and xylem, and what plant structures determine whether the organism will grow in height, girth, or both. And while the stem functions to support the plant's branches and leaves, in some plants the stem is also the site of photosynthesis.

Although our biology is significantly different than that of plants, scientists are discovering more and more similarities. We share quite a bit of DNA, thrive in moderate temperatures, have a circadian rhythm of rest and activity, require water for life, and can sense our environment and respond. Some scientists suggest that plants might even have developed a type of "hearing."
