Flashcards

Types of gymnosperm cones

Gymnosperms have male cones and female cones.

Male reproductive structure

The male reproductive structure consists of pollen grains, which are microspores.

Female reproductive structure

The female reproductive structure contains megaspores, found in female cones.

Result of fertilization

Fertilization in gymnosperms leads to the development of a diploid seed.

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
