Answer to Question 1

A

Answer to Question 2

ANS:Plants
that have taproot systems have the ability to survive periods of drought. Because they grow
deep into the soil and have few fine secondary roots, taproots do not stabilize the soil well. Fibrous
roots are generally thin, somewhat hair-like, and numerous. The fibrous root system is normally
shallow. Grasses, corn, and many ornamentals, such as Begonia, are good examples of plants with
fibrous root systems. There are many small, thin-branched roots in this type of system. The result is
that they are able to hold soil much better than taproot systems. However, fibrous root systems dry out
more easily. They cannot tolerate drought conditions.
