Female gametophyte of angiosperms is represented by
ovule
megaspore mother cell
embryo sac
nucellus
Parthenogenesis is
development of embryo without fertilization
development of fruit without fertilization
development of fruit \vithout hormones
development of embryo without egg
Male gametophyte of angiosperms is shed as
four celled pollen grain
three celled pollen grain
microspore mother cell
anther
Double fertilization and triple was discovered by
Hofmeister
Nawaschin and Guignard
Leeuwenhoek
Strasburger
Sperm and egg nuclei fuse due to
base pairing of their DNA and RNA
formation of hydrogen bonds
mutual attraction due to differences in electrical charges
attraction of their protoplasts
A diploid female plant and a tetraploid male plant arc crossed. The ploidy of endosperm shall be

Which is correct
gametes are invariably haploid
spores are invariably haploid
gametes are generally haploid
both spores and gametes are invariably
