Production of the Lignin Molecule in Xylem Cells Is an Adaptation

question 41

Multiple Choice

Production of the lignin molecule in xylem cells is an adaptation that gives what terrestrial plant benefit to vascular plants?

• A) Lignin provides strength for the plant to grow tall, and with branches.
• B) Lignin allows the xylem to transport the sugars produced in photosynthesis, without reaction that would break them apart.
• C) Lignin is a waxy molecule that reduces water loss to the atmosphere, as water is pumped throughout the plant.
• D) Lignin works within the xylem cells to promote active transport pumping of water and nutrients in each cell.
• E) Lignin reacts with CO₂ in the water, transforming it to O₂, which is necessary for photosynthesis.
