False - (ANSWER)All parts of the root tip absorbs water (root hairs)
True - (ANSWER)Adding mulch to a garden area benefits plants by decreasing water lost to evaporation
True - (ANSWER)The best way to distinguish between simple and compound leaves is to look where the

List two functions of roots - (ANSWER)Absorb water , keep plant upright and stable in the ground.
List two functions of stems - (ANSWER)Support leaves/ flowers ; transport water, food; propagate; store

, MASTER GARDENER FINAL EXAM 2026/2027 ACTUAL QUESTIONS
WITH VERIFIED ANSWERS.
When plants photosynthesize, they always make more food than is needed at that point in time. Why? -
(ANSWER)Excess food is stored for later use; this is to ensure the plants survival when photosynthesis is
limited or non-existent. Some examples may include night, extreme cold, extreme heat, etc.
Photosynthesis also releases more oxygen than the plant needs and the excess is available to other
organs.
in a stem, the terminal bud is - (ANSWER)located at the end of the stem; has meristematic tissue; can be
dominate over the auxiliary or lateral bud.
Decreases - (ANSWER)As the amount of sunlight decreases, the rate of photosynthesis
An example of a fruit that does not have chilling requirements - (ANSWER)Oranges
An example of a light that is HIGH in the BLUE range - (ANSWER)Fluorescent
Photoperiodism refers to the amount of time a plant is exposed to a light in order for flowers to bloom -
(ANSWER)Length of nighttime
During the process of photosynthesis - (ANSWER)Food in form of sugar is Made; solar energy is
converted into chemical energy.
The correct equation for photosynthesis is? - (ANSWER)6CO2 + 6H2O>>>>>>>>>C6/H12/O6 + 6 O2
How does transpiration benefit plants? - (ANSWER)Cooling of plant tissue and transporting nutrients
that are dissolved in the water
In a stem, the terminal bud: - (ANSWER)Is located at the end of of the stem; has meristematic tissue; can
be dominate over the auxiliary or lateral bud.
