Function. The function of part of an organisms is the way in which the part helps maintain the organisms to which it belongs alive and able to reproduce; or sometimes it means simply the way it works, the processes going on in it. See Adaptation (Evolutionary).

Fungicide. Any substances such as captan or benonryl that kills fungi.

Fungistasis. The inhibitions of further fungal growth.

Furauosering. A monosaccharide having a five membered ring structure.

GA₃. It stands for Gibberellic acid. It causes stain elongation.

Galactose. A simple sugar, C₆H₁₂O_6‑, stere-oisomeric with glucose, that occurs naturally as one of the products of the enzyme digestion of milk sugar lactose and as a constituent of gum arabic.

Gamates. These are sexually production haploid bodies.

Gametangium. Organ in which gametes are produced.

Gamete. A reproductive cell that fuses with another gamete to form a zygote. Examples of gametes are ova and spermatozoa. Gametes are haploid, i.e., they contain half the normal (diploid) number of chromosomes; thus when two fuse, the diploid number is restored (see fertilization). Gametes are formed by meiosis.

Gametic meosis.
The diploid organisms undergo meiosis before sexual reproduction and form four haploid gametes. These gametes fuse together in pairs to form the diploid individuals. This is the formation of haploid gametes. This is called gametic meiosis.
