of all bryophytes, their sporophytes are most similar to those of vascular plants.
their sporophytes have stomata.
their cells contain multiple small chloroplasts.
they are able to fix atmospheric nitrogen.

Explanation:

Hornworts have photosynthetic gametophytes. Among bryophytes, their sporophytes are most similar to those of vascular plants and have stomata. They can fix atmospheric nitrogen with the help of symbiotic cyanobacteria. Their cells contain a single large chloroplast, not multiple small ones.

Answer:

• Their gametophytes are photosynthetic.
• Of all bryophytes, their sporophytes are most similar to those of vascular plants.
• Their sporophytes have stomata.
• They are able to fix atmospheric nitrogen.
