Question

A scientist traversing a remote wooded area discovers what he thinks is a new plant species. He makes observations of the plant, discovers that it produces a nut similar to an acorn, and concludes it is what type of plant?
a. Gymnosperms
b. Angiosperms
c. Brynophytes
d. Pteridophytes

Answer 1

b. Angiosperm

Explanation:

Acorn is the fruit of oak tree. It is a nut and bears only one seed.

Since the scientist finds that the fruit produced on the tree is a nut then it is obviously an angiosperm because:

The only groups of seeded plant are Gymnosperms and Angiosperms.

Gymnosperms produce cones and have naked seed.

The seed produced within a fruit is a characteristic of angiosperm.
