Question

Sap

ids use specialized organs to pierce a plant and suck out
underside of leaves. During feeding, they can inject a toxin that slows plant
growth. Which pathway would the toxins most likely travel when first inside
the plant?
O A. Phloem
OB. Stem
OC. Roots
O D. Xylem

Answer 1

Toxins injected by sap-sucking insects into a plant would most likely travel through the phloem.

Step-by-step explanation:

When toxins are injected by sap-sucking insects into a plant, they would most likely travel through the phloem first. The phloem is responsible for transporting sugars and other organic compounds from the leaves to other parts of the plant. Since sap-sucking insects are primarily found on the undersides of leaves, the toxins would enter the phloem through the leaf veins where the insects have been feeding.
