Chapter 28, Problem 8TYU
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.

Students have asked these similar questions
We say that movement is a characteristic of living organisms but we always don’t see visible movements in plants. Comment.
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?
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!

- Directions: Plants have two life stages. The gametophyte life cycle, wherein a haploid spore is produced, and the sporophyte life cycle wherein there is union of the gametes. Below are different events in the development of flowering plants. Arrange them in the correct order. Place the number from 1 to 6 inside the box. The hypocotyl pushes to the soil along with the cotyledon(s). It starts as a seed which contain the miniature plant called embryo. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm Mature plant develops the gametes, releases the pollen and pollinates the flower. It is the process wherein seeds are transported, spread or moved away from the parent plant either by wind, water, animals or insect. The plant, given enough nutrients will develop in a mature stage.
