Mature Embryo Sac Structure Angiosperm — a labelled NEET Biology diagram with a definitions lexicon.
Mature Embryo Sac Structure (Angiosperm) Labelled parts: Antipodal Cells, Central Cell, Polar Nuclei, Egg Cell, Synergids, Filiform Apparatus, Micropyle, Funiculus, Nucellus, Integuments, Embryo Sac. The female gametophyte of angiosperms, typically a 7-celled, 8-nucleate structure consisting of egg apparatus, central cell, and antipodals. Cellular thickening in the synergids that guides the pollen tube into the embryo sac during fertilization. Two nuclei located in the central cell of the embryo sac that fuse with a male gamete to form the triploid primary endosperm nucleus.
