Plant Propagation Quiz

What is the process by which most leaf cuttings form adventitious buds?

• Pollination

• Photosynthesis

• Transpiration

• Wound response

What happens when secondary meristem dedifferentiates cells into new meristematic cells?

• Leaves are cut from the plant

• Adventitious roots are established

• Veins are wounded

• New shoots emerge from tissue beneath the epidermis

What is a unique characteristic of the Piggyback plant?

• It has specialized vascular cambium

• It produces plantlets

• It forms preformed roots

• It grows adventitious buds

When do wound-induced roots develop?

• During photosynthesis

• When the plant is pollinated

• After a cutting is made

• When the stem piece is cut

What is the first step in the wounding response of a plant?

• Cells near the vascular cambium and phloem begin to divide

• Cells behind the wound begin to divide and form a callus

• Outer layer of the injured cell dies and suberin seals the wound

• New shoots emerge from tissue beneath the epidermis

What are preformed roots?

• Roots that emerge after adventitious roots have been established

• Roots that develop in response to wounding

• Roots that form from adventitious buds

• Roots that develop naturally on stems while still attached to the parent plant

What happens when cellular tissue in a leaf or stem cutting dedifferentiates?

• The cutting develops callus tissue

• The cutting forms adventitious roots

• The cutting initiates new cellular divisions

• The cutting regresses from specialized function to a simpler state

What is callus tissue?

• A specialized tissue that forms adventitious roots

• A tissue that forms after the cutting is made

• A tissue that develops from preformed roots

• A bundle of undifferentiated cells that cover the wound

What is the most widely applied method for propagation using a piece of leaf or stem?

• Cutting

• Transpiration

• Pollination

• Photosynthesis
