1. What is the main difference between gymnosperms and higher spore plants? Why did these plants get this name? 2. Give a brief description of gymnosperms. 3. What is the difference between the life cycle of gymnosperms and the life cycle of bryophytes and what brings them closer to ferns, horsetails and lycopods? 4. Prove the benefits of seed propagation over spore

1. The main difference is reproduction. Higher spore plants reproduce by spores, and gymnosperms reproduce with the help of wind or animals.

2. Gymnosperms are higher plants, no water is required for reproduction, heterosexual, mostly arboreal (no grasses, there are shrubs), long-livers and evergreens.

3. Firstly, for the reproduction of bryophytes, water is needed, for gymnosperms, as we found out, no. Secondly, in bryophytes, the stem and leaves are well developed (the formation of a gametophyte), in gymnosperms it is reduced.

4. The seeds contain much more nutrients, and the seeds are much better protected from adverse conditions than spores.
