Hornworts get their name from which of the following features?

1. Liver-like lobed thallus

2. Elongated sporophyte

3. Single-celled rhizoids

A

Answer: 2. Elongated sporophyte

The division of Bryophyta consists of three different types of bryophytes. The bryophytes include the hornworts, the liverworts, and the mosses. Although all plants under the division Bryophyta are non-vascular, they have unique features that separate them.

Hornworts are classified as a separate group from the others due to their horn-like feature called the sporophyte. The gametophytes of hornworts are green and flat-shaped. Some examples include Notothylas, Anthoceros, etc.
