Select all true statements about hornworts..
The spores are diploid cells containing genetic information about the plant itself, thus making it capable of asexual reproduction. However, plants are also capable of sexual reproduction by means of the union of a sperm and an egg. The basic function of the sporophyte is to create spores – that much is known already.
Abstract. The hornworts are a small group of land plants, consisting of only 11 families and approximately 220 species. Despite their small size as a group, their phylogenetic position and unique biology are of great importance.

Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface ( e.g., their leaves). Most of them only grow a few centimeters in height, and since they don't need …Liverworts are one of three classes in the plant phylum Bryophyta. The other two classes are mosses and hornworts. Liverworts are small green terrestrial plants. They do not have true roots, stems, or leaves. Instead, they have an above ground leaflike structure, known as a thallus, and an underground structure, known as a rhizoid.
Seedless non-vascular plants are small, having the gametophyte as the dominant stage of the lifecycle. Without a vascular system and roots, they absorb water and nutrients on all their exposed surfaces. Collectively known as bryophytes, the three main groups include the liverworts, the hornworts, and the mosses.

Like all bryophytes, the dominant life phase of a hornwort is the haploid gametophyte.This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter.
