Solution
1. True. In liverworts dominant haploid generation is found whereas in case of vascular plants
the dominant generation is diploid sporophyte.
2. Option D is the correct answer. Seedless vascular plants have motile sperms and this is the
reason why these plants are found in moist environment.
3. Option D is the correct answer. Ginkgo has one surviving species. It is also known as living
fossil.
