Compare and contrast organismal lifecycles that are dominated by diploid (or sporophyte, if applicable) and haploid (or gametophyte, if applicable) phases.
Homework Answers
| Haploid life cycle | diploid life cycle |
| Gametophyte is dominant | sporophyte is dominant |
| Diploid phase is short lived | haploid phase is short lived |
| The plant spent most of the time as haploid individual | the plant spent most of the time as diploid individual |
| Found in Algae and bryophytes | found in pteridophytes, gymnosperms and angiosperms |
Please rate high.

ving questions about ferns: 1. Are the spores produced by the fern sporophyte formed by mitosis or meiosis? 2. Do the spores belong to the gametophyte or the sporophyte generation? 3. Are the gametes produced by mitosis or meiosis? 4. Are the archegonia and antheridia haploid or diploid? (HINT: Think about which generation produces them) 5. Is the dominant generation for the fern the gametophyte or the sporophyte? 6. Can you suggest an ecological role for ferns?
