sperm fertilizes the egg cell and the other sperm fuses with the two polar nuclei of the large central cell of the megagametophyte. The haploid sperm and...

large central cell of the embryo sac contains two polar nuclei. The pollen tube releases two sperm nuclei into the ovule. In gymnosperms, fertilization occurs...

fertilisation in angiosperms, the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative...

also enters the synergid and fuses with the two polar nuclei of the central cell. Since all three nuclei are haploid, they result in a large endosperm nucleus...

E.; Forsberg, R. A. (1995-11-01). "Endosperm Balance Number and the polar-nuclei activation hypotheses for endosperm development in interspecific crosses...

macapuno embryo and endosperm genotypes postulated Egg nucleus (n) Polar nuclei (2n) Sperm nucleus (n) M m MM mm M MM Germinating embryo Mm Germinating...

These eight nuclei are arranged into two groups of four. These groups both send a nucleus to the center of the cell; these become the polar nuclei. Depending...

generative nuclei of the pollen grain during double fertilization to give rise to the embryo. The other generative nucleus will fuse with the polar nuclei of...

both send a nucleus to the center of the cell which then becomes the polar nuclei. The three cells left at the end of the cell near the micropylar become...

embryo, which will become the future plant. The other one fuses with both polar nuclei of the central cell to form the endosperm, which serves as the embryo's...

sticks between spheres in models. In a polar covalent bond, one or more electrons are unequally shared between two nuclei. Covalent bonds often result in the...

the part of an embryo that give rise to the shoot system of a plant. Polar nuclei – Radicle – initial root-determined cells (Root apical meristem). Scutellum...

embryo of the seed, usually triploid, originating from the fusion of both polar nuclei with one gamete after the fertilization of the egg. 2.  (gymnosperms)...

neutral mixture of nuclei, electrons, and positrons, while others are consistent with jets composed of positron–electron plasma. Trace nuclei swept up in a...

energy. Such particles include atomic nuclei, electrons, muons, charged pions, protons, and energetic charged nuclei stripped of their electrons. When moving...

the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis is an equational division which gives rise to...

directly measured for atoms having quadrupolar nuclei (2H, 14N, 81,79Br, 35,37Cl or 127I). These nuclei are generally objects of NQR nuclear quadrupole...

material made of the heavier nuclei is made into a target, which is then bombarded by the beam of lighter nuclei. Two nuclei can only fuse into one if they...

divides the nuclei into anterior, medial, and lateral groups. The thalamus derives its blood supply from a number of arteries: the polar artery (posterior...

flare or in interplanetary space by a coronal mass ejection shock. Other nuclei such as helium and HZE ions may also be accelerated during the event. These...
