1. Plant Reproduction They can have fun too!!!!

2. I. General plan of alternation of generations A.Meiosis occurs in sporangia B.Spores released C.Independent haploid generation grows D.Possesses specialized tissues 1.Antheridia 2.Archegonia

3. E. Fertilization occurs in the archegonium F. Zygote forms G. Grows by mitosis into mature diploid plant H. Sporangia develops someplace Meiosis occurs in sporangia producing spores

4. II.Mosses A.Bryophytes –1. no true plant organs –2. no true tissues –3. traps water like a sponge –4. cannot grow very tall

5. B. Moss reproductive cycle 1. meiosis 2. protonema 3. gametophyte generation 4. archegonium 5. antheridium 6. fertilization 7. zygote 8. sporophyte generation 9. sporangia
