Definition
•Apical meristems=regions of cell division at roots/shoots.
•Embryophytes=contain multicellular, dependent embryos
•Alternation of generations=2 multicellular body forms (sporophyte, gametophyte)
•Sporangia-> walled spores
–Sporopollenin
•Multicellular gametangia (in all but Anthophyta) [p. 603]
–Antheridia, Archegonia |

Term
| alternation of generations |
|
Definition
1. Gametophyte (n)→haploid gametes (mitosis)
2. 2 gametes fuse (fertilization)→ diploid zygote
3. Zygote (2n) develops into sporophyte
4. Sporophyte (2n)→ haploid spores (meiosis)
5. Haploid spores develop into gametophytes (n |
