Detailed explanation-1: -The endosperm in gymnosperm is formed before fertilization. 4. It is haploid because it is formed from the repeated division of the haploid megaspore.
Detailed explanation-2: -Endosperm in gymnosperms is a pre-fertilization product, formed before fertilisation. Ovules transform into seeds after fertilisation. Cotyledons are produced during formation of embryos and have stored food reserves in the seed. The embryo is formed from the zygote after fertilisation.
Detailed explanation-3: -Final answer: Endosperm of angiosperms forms after fertilization from the diploid nucleus.
Detailed explanation-4: -The endosperm of gymnosperm is formed by triple fusion.
Detailed explanation-5: -In gymnosperms, when the nuclei of the two sperm meet the egg cell, one nucleus dies and the other unites with the egg nucleus to form a diploid zygote. The fertilized egg undergoes mitosis to begin the development of a new sporophyte generation-the multicellular embryo of the seed.
