Practice Exam 2
Below are sample questions from your book (of which all of the answers are in the back). These
are not necessarily indicative of the specific material or types of questions that Drs. Hofmockel
& Serb will ask on the exam. Remember, they want you to be able to apply your knowledge of
the material learned in class and from the book and part of that comes from understanding the
significance, application, and importance of that information. The majority of questions will
come from the learning objectives so focus on those more than anything else! Good luck!

What are “plants” and where did they come from?
Adaptations associated with transitioning from an aquatic to a terrestrial
environment
Understand alternation of generations using bryophytes as an example
Understand the adaptations that foster stable internal water content (the rise
of vascular plants)
Be able to discuss the changes in plant life cycle (the significance of
sporophyte becoming dominant)
Describe how seedless plants transformed Earth’s ecology
Origin and evolutionary importance of seeds
o Be able to differentiate ovule and seed
o Describe reproductive advantage of seeds over ovules
Recognize that gymnosperms and angiosperms have different levels of
diversity and be able to explain why
The role of co-evolution in angiosperm diversification (why are there so
many angiosperm species?)
Importance of fruit production as a seed dispersal mechanism
Describe how double fertilization changes seed function (origin of
endosperm)
Understand what fungi are and where they fit in the tree of life
Be able to describe the ecological importance of fungi
