1. Double fertilization
A characteristic of angiosperms in which a pollen tube carries two sperm cells to the female gametophyte in the ovule . One sperm cell fuses with the egg cell and gives rise to a diploid embryo The other sperm cell fuses with the two polar cells to form a triploid cell that develops into the endosperm .

2. Endosperm (albumen)
Nutritive tissue in a seed; in angiosperm s it's triploid and is formed in the embryo sac after fertilization. In gymnosperm s, it's haploid and is derived from the sterile portion of the female gametophyte . Compare perisperm .

3. Endosperm
A food storage tissue that provides nutrients to the developing embryo in angiosperms ; formed from the triploid cell produced when a sperm cell fertilizes the central cell. Some endosperm is solid (as in corn), some is liquid (as in coconut).

4. Genomic formula
The method used to identify the number of sets of chromosome s within a cell or organism (i.e. its ploidy ). Each set is designated "n" so one set is n is haploid , two sets is 2n is diploid , three sets is 3n is triploid , four sets is 4n is tetraploid, etc. Also, 2n+1 is known as trisomy (i.e. two full sets plus a third copy of one of the chromosomes).

5. Ploidy
The number of sets of chromosome s within a cell or organism. Each set is designated "n" so one set is n is haploid , two sets is 2n is diploid , three sets is 3n is triploid , four sets is 4n is tetraploid, etc. Also, unspecified multiple sets (but more than two) is polyploidy , and extremely large number of sets may be designated by number (for example 15-ploid for fifteen sets).

6. Triploid
Having or being a chromosome number three times the haploid number.
