FNGLA Certified Horticulture Professional (FCHP) — Questions and Answers

Question 1: The disease triangle concept in plant pathology states that disease development requires:

A vector, a wound site, and prolonged wetness
Soil compaction, poor drainage, and a weakened host
A susceptible host, a virulent pathogen, and a favorable environment (Correct answer)
Heat, humidity, and a nutrient-deficient soil

Correct answer: A susceptible host, a virulent pathogen, and a favorable environment

The disease triangle model illustrates that plant disease occurs only when a susceptible host, a virulent pathogen, and a favorable environment all overlap simultaneously.

Question 2: Which propagation technique involves bending a branch to the ground and covering it with soil?

Grafting
Layering (Correct answer)
Tissue culture
Division

Correct answer: Layering

Layering is a vegetative propagation technique where a stem or branch is encouraged to form roots while still attached to the parent plant. By bending a branch to the ground and covering a portion with soil, the buried section develops roots before being detached to grow as an independent plant.

Maple tree
Fern
Rose bush

Correct answer: Pine tree

A pine tree is classified as a gymnosperm, which are a group of seed-producing plants that include conifers, cycads, ginkgo, and gnetophytes. The distinguishing characteristic of gymnosperms is that their seeds are 'naked,' meaning they are not enclosed within an ovary or fruit. Instead, they are typically borne on the surface of scales or leaves, often in cones.

Question 15: What term describes a plant that completes its lifecycle in one growing season?

Biennial
Annual (Correct answer)
Deciduous
Perennial

Correct answer: Annual

An annual plant is one that completes its entire lifecycle, from seed germination to producing new seeds and then dying, within a single growing season. Examples include many common garden vegetables like corn, beans, and lettuce, as well as flowers like petunias and marigolds. They are typically replanted each year.

Question 16: What is the primary function of xylem in plants?

Transporting water and nutrients (Correct answer)
Storing starch
Transporting food
Photosynthesis

Correct answer: Transporting water and nutrients

The primary function of xylem in plants is to transport water and dissolved mineral nutrients from the roots throughout the plant to the leaves. Xylem forms a continuous network of tubes, acting like a plumbing system. This upward movement of water is essential for photosynthesis, maintaining turgor pressure, and cooling the plant through transpiration.

Question 17: Which plant spacing pattern creates the most naturalistic appearance in a landscape planting?

Concentric circles around a centerpiece
