19. 
How many generations are represented in a pine seed?
 
3: seed coat from parent sporophyte, food supply from gametophyte, and sporophyte embryo

Permian
 
21. 
If the angiosperm gametophyte generation has been reduced to so few cells, why hasn't it been eliminated from the life cycle?
 
The gametophyte generation produces both the protective seed coat and nourishment for developing embryo
 
22. 
Which of the following is a key difference between seedless vascular plants and plants with seeds?
 
The spore is the agent of dispersal in the first, whereas the seed functions in dispersal in the second.
 
23. 
An example of co-evolution is:
