Plant Systematics life cycle quiz

Gametophyte

• Haploid

• Multicellular

• Develops from haploid spore through mitosis

• produces haploid gametes (sperm and egg) through mitosis

Sperm and egg

• haploid

• produced via mitosis by multicellular, haploid gametophyte

Zygote

• Unicellular

• diploid

• Develops from fusion of sperm and egg through fertilization

• Divides by mitosis to create embryo

Embryo

• Multicellular

• diploid

• structure that develops from the zygote and will eventually grow into a plant.

• produce sporophytes which are diploid and multicellular

Sporophytes

• Diploid

• multicellular

• produced by zygote through mitosis, sporophytes produce spores, which are haploid.

• Creates unicellular spores through meiosis

Spores

• unicellular

• Haploid

• Produced by meiosis inside sporophytes sporangia

• A haploid spore grows via mitosis into a multicellular, haploid structure called a gametophyte
