200 Practice Exam Questions with Answers
and Rationales
SECTION 1: PLANT CLASSIFICATION & TERMINOLOGY (Questions 1-
20)
Question 1
Which term describes plants that originated and evolved naturally in Hawaii and
are found nowhere else on Earth?
A) Indigenous species
B) Exotic species
C) Endemic species
D) Polynesian introductions
Answer: C
Rationale: Endemic species are restricted to a specific geographic area—in this
case, the Hawaiian archipelago. These plants evolved in isolation and are found
naturally nowhere else in the world.
Question 2
The term "indigenous" refers to plants that:
A) Are found only in Hawaii
B) Are found naturally in Hawaii AND elsewhere
C) Were introduced by Polynesians
D) Were introduced by Europeans
Answer: B
Rationale: Indigenous plants occur naturally in Hawaii and in other Pacific
,regions, while endemic plants are unique to Hawaii. Indigenous species arrived
through natural dispersal mechanisms like wind, waves, or birds.
Question 3
Which of the following is an endemic Hawaiian plant found only in Hawaiʻi?
A) Hala (Pandanus tectorius)
B) Noni (Morinda citrifolia)
C) ʻŌhiʻa lehua (Metrosideros polymorpha)
D) Kukui (Aleurites moluccanus)
Answer: C
Rationale: ʻŌhiʻa lehua is endemic to Hawaiʻi, meaning it is found naturally
nowhere else in the world. Kukui, noni, and hala are Polynesian introductions or
indigenous species found elsewhere.
Question 4
Which of the following is an indigenous Hawaiian plant (found both in Hawaiʻi
and elsewhere naturally)?
A) Maʻo (Hibiscus brackenridgei)
B) ʻĀkia (Wikstroemia uva-ursi)
C) Hala (Pandanus tectorius)
D) ʻIlima (Sida fallax)
Answer: C
Rationale: Hala is indigenous to Hawaiʻi, meaning it arrived naturally without
human assistance and is also found in other Pacific regions. The other options are
endemic to Hawaii.
Question 5
Polynesian introductions, also known as "canoe plants," refer to plants that were:
A) Naturally occurring on all Pacific islands
B) Brought to Hawaii by early settlers for food, medicine, and materials
,C) Accidentally introduced by modern shipping
D) Endemic to Hawaii but later spread worldwide
Answer: B
Rationale: Polynesian introductions, or "canoe plants," were intentionally
transported by early Polynesian voyagers and include kukui, kalo, ʻulu, noni, and
ti. These plants were essential for survival and cultural practices.
Question 6
Which of the following is a Polynesian introduction (not native to Hawaii)?
A) Koa (Acacia koa)
B) ʻŌhiʻa lehua (Metrosideros polymorpha)
C) Kukui (Aleurites moluccanus)
D) Naupaka kahakai (Scaevola taccada)
Answer: C
Rationale: Kukui (candlenut) was brought by Polynesian settlers and is not native
to Hawaii, though it has naturalized widely. Koa and ʻōhiʻa are native; naupaka
kahakai is indigenous.
Question 7
The study of plant classification and identification is called:
A) Ecology
B) Taxonomy
C) Horticulture
D) Botany
Answer: B
Rationale: Taxonomy is the science of naming, describing, and classifying
organisms, including plants. It provides the systematic framework for identifying
and organizing plant species.
