_____ is a sticky structure, a landing platform for pollen
Stigma is a sticky structure, a landing platform for pollen
Ovary contains one or more ______
Ovary contains one or more ovules
______ ___ is located inside ovule
Embryo sac is located inside ovule
Each ovule has 1 ________ ______ ____ / _________ (2n)
Each ovule has 1 megaspore mother cell / megasporocyte (2n)
Each megasporocyte divide by ______ to produce 4 haploid ________
Each megasporocyte divide by meiosis to produce 4 haploid megaspore
The 3 megaspores near ________ will degenerate, 1 megaspore remains
The 3 megaspores near micropyle will degenerate, 1 megaspore remains
Surviving megaspore undergo _______ 3 times to form ______ ___
Surviving megaspore undergo mitosis 3 times to form embryo sac. Embryo sac contains 8 nuclei
Megasporangium is
A chamber within ovule in a heterosporous plant in which megaspores are produced
Megasporocyte /
megaspore mother cell is
A diploid cell in megasporangium that divide by meiosis to give rise to 4 haploid megaspores
Megaspore is
A larger haploid spore from a heterosporous plant species that develops into embryo sac / female gametophyte
Embryo sac /
female gametophyte is
A large cell that develops in the ovule of flowering plants containing 8 nuclei formed by mitotic division of the surviving megaspore
Antipodal cell is
Three haploid cells in the mature embryo sac of flowering plants that are situated at the opposite end to micropyle
Polar nuclei are
Two haploid nuclei in the center of embryo sac of flowering plants which fuse with a male gamete to form a triploid endosperm
Egg cell / ovum
The mature, unfertilized, non-motile female reproductive cell
Synergid cells are
The two short-lived haploid cells in the embryo sac of flowering plants that are closely associated to the egg cell
