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
Point out the odd one
mycropyle
pollen grain
Male gametophyte of angiosperms/monocots is
microsporangium
microspore
stamen
Which is correct
gametes are invariably haploid
spores are invariably haploid
gametes are generally haploid
both spores and gametes are invariably
A diploid female plant and a tetraploid male plant arc crossed. The ploidy of endosperm shall be
tetraploid
triploid
diploid
pentaploid
Development of an organism from female gamete/
adventitive embryo
polyembryony
parthenocarpy
parthenogenesis
Generative cell was destroyed by laser but a normal pollen tube was still formed because
vegetative cell is not damaged.
contents of killed generative cell stimulate pollen growth
laser beam stimulates growth of pollen tube
the region of emergence of pollen tube is not
Pollination occurs in
bryophytes and angiosperms
pteridophytes and angiosperms
angiospernis and gymnosperms
angiosperms and fungi
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
