How can Tracie reduce stress on greenhouse-produced seedlings at transplanting time before removing them from the greenhouse?
Fertilize the seedlings more
Harden off the seedlings
Mist the seedlings often
Water the seedlings more
Samantha is cutting the iris rhizome in sections. This method of asexual propagation in which plants are broken or cut into smaller pieces or clumps and are planted to form new plants is:
division
grafting
layering
seeding
The plant process by which all food is manufactured is:
absorption
photosynthesis
respiration
translocation
When a plant first begins growing from a seed, the stage of growth is:
dormant
juvenile
mature
reproductive
The main product of photosynthesis is:
carbon dioxide
nitrogen
sugar
water
The process of moving synthesized and absorbed food and nutrients within the plant is:
photosynthesis
respiration
reproduction
translocation
Janet uses stem cuttings to propagate her prize-winning azaleas. What is the best time of day for Janet to take the cuttings from her azaleas?
early evening
early morning
late afternoon
mid-day
Victor joins a new variety of pecan tree to some rootstock he has grown from seeds. Which propagation method does he use?
grafting
hardwood cuttings
layering
softwood cuttings
When compared to the amount of oxygen produced in the process of photosynthesis, the amount of oxygen used in plant respiration is:
about the same
less
more
much more
Vegetative growth is the growth of:
flowers and fruits
fruits and roots
leaves, stems, roots
roots, seeds, flowers
Christy enjoys mound layering her prize-winning azalea. Which is true of her mound layering technique?
The plant has to be dug and separated first.
A trench has to be dug for each stem being propagated.
Only one inch of bark has to be removed.
Soil has to be heaped up around the plant.
Jacob learns a disadvantage of propagating using cuttings is that when cuttings are removed from the parent plant, the:
cuttings’ absorption process stops.
cuttings are cut off from their source of water.
parent plant needs more light.
parent plant needs additional fertilizer.
Caroline is careful to use tissue culture in laboratory conditions that are aseptic. Therefore, the laboratory environment is:
dirty
humid
pretty
sterile
Hannah is hardening off some tomatoes started in the greenhouse. Which is she reducing to harden off her plants?
fertilizer and air
humidity and water
lime and phosphate
soil and fertilizer
Callie is propagating her African violet by taking leaf cuttings. She is confident that leaf cuttings will work because she is using:
axillary buds
herbaceous plants
stem tissue
woody tissue
Water loss from the leaf surface through evaporation is the plant process called:
absorption
photosynthesis
respiration
transpiration
Andrew selects a unique azalea plant. The propagation method that he uses to rapidly increase the number of identical plants is:
grafting
leaf cuttings
seeding
tissue culture
If Dave has a bag of fescue that has a seed germination rate of 80%, he can expect:
20 out of 80 seeds to germinate
20 out of 100 seeds to germinate
80 out of 100 seeds to germinate
all seeds to germinate
In which stage of growth do plants rest or grow very little?
dormant
intermediate
juvenile
reproductive
The by-product of photosynthesis is:
carbon dioxide
nitrogen
oxygen
water
Victoria is careful to study the temperature, moisture, and seed viability for the plants she plans to grow. These are factors that affect:
germination rates
hardwood cuttings
softwood cuttings
tree grafts
Jenny needs to construct some beds to use for rooting azalea cuttings. How deep should the rooting media be?

Jamie has a tray of marigold seedlings she started from seed. She transplants the seedlings from the seedling flat to cell packs when the:
first mature roots appear
first true leaves are on the plant
plants are 2 weeks old
seedlings are 6 inches tall
Uneek is making leaf cuttings. She must be certain that she cuts the leaf:
margin
petiole
stomate
vein
Plant roots take water from the soil through the process of:
absorption
photosynthesis
reproduction
respiration

50
1,000
1,200
2,000
Jennifer is using Rootone on her poinsettia cuttings. She knows that an advantage of using hormones on cuttings is that they:
aid in photosynthesis
decrease water needs
keep the leaves from dropping
seed root development
Neil is sexually propagating some plants. Which plant parts will he use?
leaves
roots
seeds
stems
The chemical formula for photosynthesis is:
6CO2 + 6H20 → C6H12O6 + 6O2.
C6H12O6 + 6O2 → 6CO2 + 6H2O.
NH4NO3 + 4H2O → 6NaCl + 4H2O.
4P2O5 + 6CO2 → 6H2O + 4CaCO3.
