There are two groups of plants. Vascular plants are plants containing tubes which carry food and water throughout the plant. Most plants are vascular. Non-vascular plants do not have tubes to carry food and water throughout the plant. Mosses are non-vascular.
All plants grow and adapt to their environment.
These adaptations take the form of various structures and behaviors in the plant. This chapter reviews how both vascular and non-vascular plants grow and adapt to their environment. Plant Response Behaviors in plants, like animals, depend on factors in the environment. Their behaviors often are controlled by hormones. They also respond to stimuli, such as light, gravity, and touch.
