Question

A friend has discovered a new plant and brings it to you to classify. The plant has the following characteristics: a taproot system with growth rings evident in cross section and a layer of bark around the outside. Which of the following best describes the new plant?

a. herbaceous monocot

b. woody eudicot

c. woody annual

d. herbaceous eudicot

e. woody monocot

Answer 1

Woody eudicot is most likely the correct answer.  Growth rings implies a perennial plant.  Most monocots have fibrous root systems rather than a taproot.  Woody annual would not show any growth rings as it would die during winter.  Herbaceous dicots are usually annuals and wouldn't show growth rings and would lack bark.
