Question

All land plants have single cell haploid and single cell diploid states single cell haploid and multicellular diploid states multicellular haploid and single cell diploid states multicellular haploid and multicellular diploid states A. B. C. D. E. diplontic life cycles 7. A gametophyte is B. c. 2n 3n 4n 5n A sporophyte is In 2n 3n C. D. E. 9. The dominant (bigger) state in mosses, liverworts, and hornworts is the A gametophyte sporophyte C. sporangium D. archegonium E. antheridium 10. The dominant (bigger) state in ferns, horsetail fems, and whisk ferns is the A. B C. gametophyte sporophyte sporangium archegonium antheridium

Answer 1

6) all land plants have both haploid and diploid stages, the haploid gametophyte and diploid sporophyte are multicellular so the answer is D) multicellular haploid and multicellular diploid states.

7) gametophyte is haploid and the sporophyte is diploid, haploid contains only one set of chromosomes, so it is represented as 1n. so the answer is A) 1n.

8) sporophyte is diploid, so there are two sets of chromosomes diploid is represented by 2n so the answer is B) 2n.

9) in bryophytes the haploid gametophyte is the dominant stage and the diploid sporophyte is dependent on the haploid sporophyte, so the answer is A) gametophyte.

10) in ferns the dominant stage is the diploid sporophyte the spores produced by meiosis of the sporophyte, germinate to produce haploid gametophyte, the gametophyte is not dependent of the sporophyte, the gametophyte is short-lived compared to sporophyte so sporophyte is the dominant stage so the answer is B) sporophyte

( antheridium produces the male gamete, and archegonium produces female gamete)
