Chapter 1 - The Plant Kingdom
1. Historically, there have been five kingdoms of living things.
a. True
b. False
ANSWER: False
RATIONALE: Historically, there have been two kingdoms of living things—plants and animals. Recent trends in
classification have modified that system to include five kingdoms based on evolutionary origins and
relationships.

2. Green plants form the base of the food chain.
a. True
b. False
ANSWER: True
RATIONALE: Because of their photosynthetic processes, green plants form the base of the food chain and thus the
beginning of the energy flow through an ecosystem as shown in Figure 1-2. They are also the only
important organisms able to take in inorganic elements and incorporate them into organic
compounds in living tissues.
