Questions with Answers & Rationales
Exam Blueprint
SECTION 1: Basic Horticulture & Plant Science
1. What is the process by which plants convert sunlight, water,
and carbon dioxide into glucose and oxygen?
A. Respiration
B. Photosynthesis
C. Transpiration
D. Fermentation
Answer: B
Rationale: Photosynthesis is the process where plants use
chlorophyll to capture light energy, converting CO2 and water
into glucose and oxygen in the chloroplasts.
2. What is the primary function of plant roots?
A. Photosynthesis
B. Anchorage, water absorption, and nutrient uptake
,https://www.stuvia.com/user/performance
C. Reproduction
D. Gas exchange
Answer: B
Rationale: Roots anchor the plant in the soil, absorb water and
dissolved nutrients, and store energy in some species.
3. What is the function of stomata in plant leaves?
A. To absorb sunlight
B. To regulate gas exchange (CO2 in, O2 out) and water loss
through transpiration
C. To transport water
D. To store glucose
Answer: B
Rationale: Stomata are microscopic pores on leaf surfaces that
open and close to regulate gas exchange and water loss through
transpiration.
4. What is the difference between an annual and a perennial
plant?
A. Annuals live for multiple years; perennials live for one season
B. Annuals complete their life cycle in one growing season;
perennials live for multiple years
,https://www.stuvia.com/user/performance
C. Both live for multiple years
D. Both complete their life cycle in one season
Answer: B
Rationale: Annuals germinate, grow, flower, set seed, and die
within one growing season. Perennials regrow each year from
the same root system.
5. What is a biennial plant?
A. A plant that lives for two years, flowering and setting seed in
the second year
B. A plant that lives for one season only
C. A plant that lives forever
D. A plant that flowers twice per year
Answer: A
Rationale: Biennials complete their life cycle over two years,
typically growing vegetatively in year one and flowering/setting
seed in year two.
6. What is the term for a plant that loses its leaves in the fall?
A. Evergreen
B. Deciduous
C. Coniferous
D. Herbaceous
, https://www.stuvia.com/user/performance
Answer: B
Rationale: Deciduous plants shed their leaves annually, usually
in autumn, and regrow them in spring.
7. What is the term for a plant that retains its leaves year-
round?
A. Deciduous
B. Evergreen
C. Annual
D. Biennial
Answer: B
Rationale: Evergreen plants retain their foliage throughout the
year, though they may shed older leaves gradually.
8. What is the primary purpose of flowers in plants?
A. Photosynthesis
B. Sexual reproduction (attracting pollinators and producing
seeds)
C. Water absorption
D. Nutrient storage
Answer: B
Rationale: Flowers contain reproductive structures (stamens
