Detailed Diagram Of The Mature Embryo Sac Showing All 7 Cell
Detailed Diagram Of The Mature Embryo Sac Showing All 7 Cell — a labelled NEET Biology diagram with a definitions lexicon.
Detailed diagram of the mature embryo sac showing all 7 cells and 8 nuclei. Labelled parts: Cross-section, Polar Nuclei, Central Cell, Embryo Sac, Egg Cell, Integuments, Synergids, Micropyle, Nucellus, 8 nuclei, Labels must include, Antipodals. A diagrammatic view of an organ or tissue obtained by cutting it at a right angle to its longitudinal axis. FYI: Transverse sections (T.S.) are standard in plant anatomy to study the arrangement of vascular bundles. Two nuclei located in the central cell of the embryo sac that fuse with a male gamete to form the triploid primary endosperm nucleus. The largest cell of the embryo sac containing two polar nuclei that fuse to form a diploid secondary nucleus. FYI: The triple fusion of a male gamete with the polar nuclei results in the triploid endosperm. The female gametophyte of angiosperms, typically a 7-celled, 8-nucleate structure consisting of egg apparatus, central cell, and antipodals. The female gamete located within the egg apparatus at the micropylar end of the embryo sac. FYI: Syngamy occurs when one male gamete fuses with the egg cell to form a diploid zygote. The one or two protective envelopes surrounding the megasporangium (nucellus) of an ovule. FYI: After fertilization, the integuments harden to become the seed coat, consisting of the testa and tegmen. Two haploid cells at the micropylar end of the embryo sac that help guide the pollen tube. FYI: They possess a filiform apparatus which plays a key role in directing the pollen tube's entry. A small opening in the integuments of an ovule through which the pollen tube enters. FYI: In seeds, it remains as a small pore to facilitate water and oxygen entry during germination. The central mass of parenchymatous tissue within the integuments of an ovule that contains the embryo sac. FYI: One of its cells differentiates into the Megaspore Mother Cell (MMC) during megasporogenesis. 8 nuclei is a key labeled feature or concept in this BioAtlas visual: A highly detailed, labeled cross-section of a Polygonum type embryo sac.
