Ivy is a plant with long, thin stems. Because its stems are not very strong, an ivy plant cannot grow straight up by itself. The ivy stems have a sticky liquid. Like glue, this liquid helps the ivy stick to tree trunks. Ivy is found in areas where there are a lot of large trees.

Answer 1

B. They help ivy plants grow up trees to get more sunlight.

The stems of ivy are designed to allow the plant to climb up trees to reach sunlight, which is important for its survival and growth. The sticky liquid on the stems assists in adhering to tree trunks, helping the plant elevate itself towards light sources.
