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
