NOTE: these are not comprehensive, i.e. they do not cover all of the material that will be covered
on the upcoming exam. Remember that the exam will also have 10-20 points’ worth of short
answer questions as well. Exam 2 covers:
Plant Growth (beginning with slide 23 of plant form and function)
Plant Water and Sugar Transport
Plant Nutrition
Plant Sensory Systems
Fungi
Introduction to Animals
Protostomes
Deuterostomes up through end of Wednesday March 23
Sample True or False Questions:
1. Current evidence indicates that fungi are more closely related to animals than to
plants.
2. The vascular cambium produces secondary xylem to the inside and primary xylem to
the outside.
3. A fungus is diploid throughout most of its life cycle.
4. Many animals, although they are diverse, possess very similar developmental genes.
