tip layering
Which is considered a biotech method of plant propagation?
cuttings
grafting
sowing seed
tissue culture
Tissue culture may be used for:
producing genetically identical plants
disinfecting greenhouse structures
sexual reproduction in floral crops
sterilization of soil products
Sexual reproduction in plants is the propagation of plants by:
flowers
roots
seeds
stems
The three primary nutrients supplied in a complete fertilizer are:
carbon, hydrogen, and oxygen
nitrogen, phosphorus, and potassium
calcium, magnesium, and sulfur
carbon, nitrogen, and sulfur
Sulfur is used to lower soil pH so that the soil will become more:
acidic
alkaline
eroded
porous
The purpose of a seed coat is to:
store food
store genetic material
protect the seed
filter light
The primary function of the root is to:
make sure that the plant will grow
anchor the plant and supply water and nutrients
ensure that the plant can be propagated
hold up the stem of the plant and provide propagation material
The primary function of the stem is to:
produce flowers
produce fruit
anchor the plant
support other plant functions
What type of fertilizer is animal manure?
complete
inorganic
lime
organic
Foliar application of fertilizer is applied by:
injecting the fertilizer in the soil below the plant
placing the fertilizer in a band on either side of the row
sprinkling the fertilizer on the ground beside the plant
spraying the fertilizer on the leaves of the plant
The three parts of a seed are:
root, stem, and flower
root, seed coat, and endosperm
embryo, cotyledon, and new plant
seed coat, endosperm, and embryo
The purpose of petals in flowers is to:
attract insects for pollination
support the stamen
store food for young seeds
hide the plants from animals
Organic fertilizers made from dried and pulverized manure are:
balanced sources of plant nutrients
caustic to plants and can cause injury
in soluble form and quickly available to plants
slow-acting and long-lasting
Propagation is defined as:
the union of egg and sperm
the process of increasing the number of a species
a cheaper method of producing plants than with seeds
the only way to propagate some species and cultivars
A procedure of fertilizer application used on row crops where the fertilizer is placed in bands about 8 inches from the row in known as:
side-dressing
top-dressing
broadcasting
foliar application

peat moss
perlite
soil
vermiculite
Grafting is a:
type of sexual propagation
type of hybridization
method by which two plant are divided
method of joining two different plants
One would likely find peat moss in waterlogged areas called:
bogs
creeks
pits
ponds
If a soil pH level is 6.0 and needs to be raised to 7.0, what amendment is BEST incorperated into the soil?
sulfur
sodium
lime
magnesium
Which is a part of the stamen?
pistil
stigma
petal
anther
Soil pH affects the availability of:
nutrients in the soil
the structure of the soil
the land class of the soil
microbes in the soil
What is applied to lower the pH value of soil?
lime
sulfur
fertilizer
sand
Which has the MOST impact on the availability of nutrients in a soil or plant growing media?
type of plants grown
improper soil or media pH
size of container
amount of air in the media
The major types of root systems are:
cell division and fibrous
cuttings and root hairs
fibrous and root cap
firbous and taproot

oxygen in the atmosphere
respiration carried on during the daylight hours
light intensity, temperature, and carbon dioxide
Food for the seed is stored in the:
seed coat
endosperm
embryo
radicle
The part of the plant that is responsible for the development of seed is the:
flower
stem
leaf
petiole
The primary function of the leaf is to:
support other plant functions
produce flowers
produce fruit
manufacture food for the plant
What kind of propagation uses vegetative plant parts to increase the number of plants?
asexual
perlite
sexual
vermiculite
