Study Notes
Gymnosperm Cones
- There are two types of gymnosperm cones: microstrobili (male) and megastrobili (female)
Reproductive Structures of Gymnosperms
- The male reproductive structure of a gymnosperm is the microstrobilus, which produces pollen
- The female reproductive structure of a gymnosperm is the megastrobilus, which contains ovules
Fertilization and Seed Development
- The result of fertilization in gymnosperms is the formation of a zygote, which develops into a seed
- The diploid stage of the conifer life cycle is called the sporophyte
Categories of Seed-Producing Plants
- The two categories of plants that reproduce using a seed are gymnosperms and angiosperms
Characteristics of Gymnosperm and Angiosperm Seeds
- The main difference between angiosperm and gymnosperm seeds is that angiosperm seeds are enclosed in an ovary, while gymnosperm seeds are not
Life Cycle of Gymnosperms
- Gymnosperms alternate between two life stages: the haploid gametophyte stage and the diploid sporophyte stage
- The male gametophyte in gymnosperms is called the microgametophyte, and the female gametophyte is called the megagametophyte
- The reproductive process in gymnosperms is called heterosporous reproduction, in which both microspores and megaspores are produced
