Question

Dune grasses help hold the sand of the sand dunes in place. The grasses can survive in high winds and flooding. What feature of dune grasses helps to keep the plants in place?

A) long, thin leaves
B) spreading, fibrous roots
C) very thick waxy covering
D) small flowers on the end of spikes

Answer 1

B. The roots of a plant help hold the plant in place, as well as keep the soil together. If you have no plants in an area, the soil will wash away (deforestation and erosion, respectively).

Answer 2

B) spreading, fibrous roots

Step-by-step explanation:

The dune grasses have the capacity to develop stabilizing roots that keep them anchored in the sand, an adaptation that protects against high winds and flooding as well as protect the dune from the forces of erosion.

Thus, the stabilizing roots can be described as spreading, fibrous roots.

The correct option is B.
