May you please help me with a short answer please. Also I dont need explanation for the answer. 15.4 Comparison of Gymnosperms and Angiosperms :Compare the adaptations of flowering plants to those of conifers Introduction Among plants, gymnosperms and angiosperms are seed plants. Review the plant evolutionary tree (see Fig. 15.1) and note that the gymnosperms and angiosperms share a common ancestor, which produced seeds, structures that contain the next sporophyte generation. We shall see that the use of seeds to disperse the next generation requires a major overhaul of the alternation-of-generations life cycle. Nonseed plants disperse the gametophyte, the n generation, when spores are carried by the wind to a new location. Seed plants disperse the sporophyte, the 2n generation. Which generation-gametophyte or sporophyte is better adapted to a land environment because it contains vascular tissue? Nonseed plants utilize an archegonium to protect the egg. After fertilization, the sporophyte develops within and remains attached to the archegonium. Seed plants protect the entire female gametophyte within an ovule. The ovule develops into a sporophyte-containing seed following fertilization. You will see that the formation of the ovule and also the pollen grains (contain male radical innovations in the life cycle of seed plants. In gymnosperms, pollen grains are windblown, but many flowering plants havea mutualistic relationship with animals, particularly flying insects, which disperse pollen within the species. Animals also disperse the seeds of many flowering plants. Relationships with animals help explain why flowering plants are so diverse and widespread today 100x ovule egg Ed Reschke 15-1 Laboratory 15 Seed Plants 181Explanation / Answer
15.4) Angiosperms and gymnosperms both have vessels and companion cells. The angiosperms and gymnosperms ovules develop into seeds. The epigeal, hypogeal, or both kind of seed germination is present. In both plants the reduced gametophytic phase is present.
