Question

Which the following group is/are plants which produce spores and embryos but lack seeds and vascular tissue?

• A. Liverworts
• B. Hornworts
• C. Mosses
• D. All of the above

Answer 1

The correct option is D All of the above

Mosses, Liverworts and Hornworts are lumped together as Bryophytes, plants lacking true vascular tissues, and sharing a number of other primitive traits. They also lack true stems, roots or leaves, though they have cells, that perform these general functions. The leafy green plant is really the gametophyte, which is the dominant stage in all Bryophytes. The sporophytes of Bryophytes do not have a free-living existence. They grow directly out of the fertilized egg in the archegonia, and remain dependent on the parent gametophyte for their nutrition. Hence the correct option is D.
