Summary Introduction
To enlist:
Some examples of exaptations in plants.
Concept introduction:
When a trait that already has a function develops (evolves) to serve another purpose, the process is called exaptations. It is a part of evolution. For example: initially the feathers were a source of warmth to the birds, but later it helped in flight.

Evolutionary biologists have coined the term exaptation to describe a common occurrence in the evolution of life. A plant organ originally has a particular function, however, fulfills a new one. Provide two examples of exaptation in plant organs and elaborate comprehensively.
Name 4 different evolutionary adaptations that allowed plants to survive on land instead of in water. Explain the significance of each adaptation-how does it help terrestrial plants?
All of the protoplasm of one plant can be considered to be one continuous mass, called the ______________ _________________. Walls and intercellular spaces of a plant are called the ___________________________ of the plant.

- EVOLUTION LINK Like stems in general, some vines are herbaceous and others are woody. Tropical rain forests have a greater diversity of vines than in any other environment on Earth, and most of these vines are woody. Develop a hypothesis to explain why natural selection has favored the evolution of more species of woody vines (as opposed to herbaceous vines) in tropical rain forests.arrow_forwardTest Your Understanding Know and Comprehend 1.
