Textbook Question
Chapter 35, Problem 9TYU
EVOLUTION CONNECTION Evolutionary biologists have coined the term exaptation to describe a common occurrencc in the evolution of life: A limb or organ evolves in a particular context but over time takes on a new function (see Concept 25.6). What are some examples of exaptations in plant organs?

Some ancestral plants had a difficult transition to land, as challenges to survive caused plant evolution to develop very specialized adaptations over an extended amount of time. These are some
of the challenges that plants faced:
A. Avoiding desiccation
B. Supporting larger bodies (against gravity)
C Internally transporting substances
D. Keeping gametes wet
E. Keeping embryos wet
For each of the above challenges. provide a structure/adaptation that plants have developed which mitigates that specific challenge. Must describe a structure or trait for all!
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?
Describe a modified structure and function of the following plant organs:
Leaf -
Stem -
Root -

This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C.
