BIO 1500
1. Angiosperms: Phylum Anthophyta• Highly specializedplants that emergedabout 100-200 million years ago•
Highly diversified; 80% of plants (about270,000 known species)3
2. Ploidy: the number of complete sets of chromosomes in a cell Haploid- 1 set Diploid 2 sets
3. Mitosis: cell division in which the nucleus divides into nuclei containing the same number of chromosomes.
"Photocopied"
4. Meiosis: Cell division that produces reproductive cells in sexually reproducing organisms
1/5
, 5. Angiospems: Sporophyte v Gametophyte: Plant Life Cycle: Alternation of Generations• In
angiosperms, sporophyte generation isdominant over gametophyte
6. Gametophyte phase location: Inside of the flower
7. Flower whorls: sepals (collectively termed"calyx") - protects reproductive organs- petals (collectively
termed"corolla") - attract pollinators- stamens (collectively termed "androecium")- carpels (collectively termed "gynoe-
cium")
