Plant Chemical Adaptations
Physical adaptations are one way plants have become well-adapted to specific environmental conditions. For example, cacti have spines in place of leaves to prevent water loss in the arid conditions of the desert, and deciduous trees lose their leaves in the fall to survive cold weather conditions over the winter. Chemical adaptations are another means for plant protection. Many plants produce toxic or noxious compounds to protect themselves from insects or animals that would eat them, to reduce competition from other plants, or even to change the response of pollinators. Humans analyze and harvest these compounds for our own benefit.
