When _______ and ________ occur together, we call it fertilisation.
Select one:
a. Plasmogamy and karyogamy
b. Mitosis and meiosis
c. Sporophyte and gametophyte
d. Haploid and diploid
a. Plasmogamy and karyogamy
Match the life cycle with the correct plant group.
Life cycle A: Spore > MITOSIS > non-vascular photosynthetic gametophyte > MITOSIS > gametes > FERTILISATION >Zygote in archegonium > MITOSIS > Vascular sporophyte > MEIOSIS > Spore
Life cycle B: Microspore/megaspore > MITOSIS > male and female gametophyte (pollen, ovule) > MITOSIS > gametes > FERTILISATION >Zygote in archegonium of ovule; becomes a seed > MITOSIS > Vascular sporophyte > MEIOSIS > Microspore/megaspore
Life cycle C: Microspore/megaspore > MITOSIS > male and female gametophyte (pollen, embryo sac) > MITOSIS > gametes > DOUBLE FERTILISATION >Zygote in archegonium of ovule, triploid endosperm; becomes a seed > MITOSIS > Flowering vascular sporophyte > MEIOSIS > Microspore/megaspore
Life cycle D: Spore > MITOSIS > non-vascular photosynthetic gametophyte > MITOSIS > gametes > FERTILISATION >Zygote in archegonium > MITOSIS > Sporophyte > MEIOSIS > Spore

Life cycle B
In _____________, double fertilization occurs. It is a complex process which happens when the egg cell and the two polar nuclei in the female gametophyte (megagametophyte or embryo sac) are each fertilized by a male gamete (sperm nuclei). A zygote and an endosperm are produced.
