Start with the diploid sporophyte. Place in correct order for angiosperm double fertilization. 2 sperm cells released from male gametophyte into embryo sac Diploid sporophyte develops Microsporangium (pollen sac on anther) bursts open Microspores produced in pollen sacs and megaspores in ovary Pollen grains land on stigma Fertilization when sperm and ovum unite Pollen tube grows from tube cell in male gametophyte into ovary Zygote formation 2 BIO101 Plant biology worksheet 8. Fill in. Each answer is used once embryo sac diploid angiosperms polar nuclei pollen tube megaspores pollen grain sperm a. A diploid megasporocyte cell undergoes meiosis to produce 4 haploid ______________, 1 of which survives. b. In the female reproductive organ of the plant, the ____________, a multinucleate structure with 8 haploid nuclei, (including ovum an polar bodies) forms. c. The male gametophyte is also known as a ____________ d. After double fertilization occurs in the angiosperm, the zygote is_____ in terms of chromosomes e.
