Which group of plants is commonly called the first land plants?
- A. Algae
- B. Bryophytes

- D. Gymnosperms
Answer: B. Bryophytes

Which of the following is the most accurate statement about alternation of generations in land plants?
- A. Only gametophyte generation is present in all plants
- B. Only sporophyte generation is present in all plants
- C. Both haploid gametophyte and diploid sporophyte generations are present
- D. All plants reproduce only by binary fission
Answer: C. Both haploid gametophyte and diploid sporophyte generations are present
Plant life cycles typically involve alternation between haploid gametophyte and diploid sporophyte generations.
