Label	Id	Description
regulation of platelet activation	GO_0010543	[Any process that modulates the rate or frequency of platelet activation. Platelet activation is a series of progressive, overlapping events triggered by exposure of the platelets to subendothelial tissue.]
regulation of cell activation	GO_0050865	[Any process that modulates the frequency, rate or extent of cell activation, the change in the morphology or behavior of a cell resulting from exposure to an activating factor such as a cellular or soluble ligand.]
secondary plasmodesma	GO_0009551	[A plasmodesma with a branched structure, often with many channels leading into a larger central cavity; found in older tissues and usually derived from preexisting primary plasmodesmata.]
negative regulation of platelet activation	GO_0010544	[Any process that decreases the rate or frequency of platelet activation. Platelet activation is a series of progressive, overlapping events triggered by exposure of the platelets to subendothelial tissue.]
negative regulation of cell activation	GO_0050866	[Any process that stops, prevents, or reduces the frequency, rate or extent of cell activation.]
microsporogenesis	GO_0009556	[The process in which the microsporocyte undergoes meiosis, giving rise to four haploid microspores.]
plant-type sporogenesis	GO_0048236	[The formation of plant spores derived from the products of meiosis. The spore gives rise to gametophytes.]
pollen development	GO_0009555	[The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates.]
box C/D snoRNA binding	GO_0034512	[Interacting selectively and non-covalently with box C/D small nucleolar RNA.]
snoRNA binding	GO_0030515	[Interacting selectively and non-covalently with small nucleolar RNA.]
antipodal cell differentiation	GO_0009557	[The process in which an uncellularized nucleus cellularizes and acquires the specialized features of an antipodal cell.]
megagametogenesis	GO_0009561	[The process whose specific outcome is the progression of the embryo sac over time, from its formation as the megaspore to the mature structure. The process begins when three of the four haploid megaspores disintegrate, and the fourth undergoes mitosis giving rise to a binucleate syncytial embryo sac. The two haploid nuclei migrate to the opposite poles of the embryo sac and then undergo two rounds of mitosis generating four haploid nuclei at each pole. One nucleus from each set of four migrates to the center of the cell. Cellularization occurs, resulting in an eight-nucleate seven-celled structure. This structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center.]
box H/ACA snoRNA binding	GO_0034513	[Interacting selectively and non-covalently with box H/ACA small nucleolar RNA.]
megasporogenesis	GO_0009554	[The process in which the megasporocyte undergoes meiosis, giving rise to four haploid megaspores in the nucellus.]
centromere separation	GO_0034510	[The cell cycle process in which centromeres are physically detached from each other during chromosome separation.]
chromosome separation	GO_0051304	[The cell cycle process in which paired chromosomes are detached from each other. Chromosome separation begins with the release of cohesin complexes from chromosomes; in budding yeast, this includes the cleavage of cohesin complexes along the chromosome arms, followed by the separation of the centromeric regions. Chromosome separation also includes formation of chromatid axes mediated by condensins, and ends with the disentangling of inter-sister catenation catalyzed by topoisomerase II (topo II).]
nuclear chromosome segregation	GO_0098813	[The process in which genetic material, in the form of nuclear chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets. Nuclear chromosome segregation begins with the condensation of chromosomes, includes chromosome separation, and ends when chromosomes have completed movement to the spindle poles.]
basipetal auxin transport	GO_0010540	[The unidirectional movement of auxin from the apex to base of an organ, including the shoot, leaf, primary root, or lateral root.]
U3 snoRNA binding	GO_0034511	[Interacting selectively and non-covalently with U3 small nucleolar RNA.]
embryo sac cellularization	GO_0009558	[The process in which the eight-nucleate single celled female gametophyte develops into the seven-celled female gametophyte. This mature structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center. An example of this process is found in Arabidopsis thaliana.]
