Horticulture I Unit 4.00 Review

The process of moving synthesized and absorbed food and nutrients within the plant is:

• translocation

• photosynthesis

• absorption

• respiration

The by-product of photosynthesis is:

• Carbon Dioxide

• Water

• Oxygen

• Glucose

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 two weeks old.

• seedlings are 6 inches tall.

The chemical formula for photosynthesis is:

• 6CO² + 6H20 → C6H12O6 + 6O2

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• NH4NO3 + 4H2O → 6NaCl + 4H2O

• 4P2O5 + 6CO2 → 6H2O + 4CaCO3

When a plant first begins growing from a seed, the stage of growth is:

• dormant

• juvenile

• mature

• reproductive

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.

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

Uneek is making leaf cuttings. She must be certain that she cuts the leaf:

• margin

• petiole

• stomate

• vein

Caroline is careful to use tissue culture in laboratory conditions that are aseptic. Therefore, the laboratory environment is:

• dirty

• humid

• pretty

• sterile

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.
