Question

Sporophyte (haploid or diploid?) Anthers contain microsporocytes, also known as An ovary contains ovules. microspore mother cells. Each ovule contains a megasporocyte, also (haploid or diploid?) known as a megaspore mother cell (haploid or diploid?) mitosis or meiosis? mitosis or meiosis? microspores (haploid or diploid?) megaspores (haploid or diploid?) (how many megaspores survive per ovule: one, two, three or four?) mitosis or meiosis? mitosis or meiosis? immature male gametophyte = "pollen grain" 2 cells: tube + generative (haploid or diploid?) female gametophyte ="embryo sac" 7 cells, 8 nuclei (haploid or diploid?) (how many eggs in one embryo sac? Fertilization Which cell divides to produce two sperm cells? (tube cell or generative cell?) (by mitosis or meiosis?). 1 sperm + egg >>> zygote (haploid or diploid?) 1 sperm + 2 polar nuclei >>> endosperm (haploid, diploid or triploid?) = "double fertilization"

Explanation / Answer

Sporophyte is diploid - megasporocyte is diploid cell in which meiosis will occur - megaspores is diploid and one survive per ovule and meiosis will happen - embryo say contain 8 nuclei, haploid and one egg in embryo say - fertilization results in diploid, endosperm is triploid and double fertilization occur.
