Computer-aided Design And Drafting (CADD) Definition - What does Computer-aided Design And Drafting (CADD) mean? Computer aided design and drafting (CADD) is a subfield of engineering which deals with the design and drafting of objects and materials through the use of specialized software that visualizes designs as modular 3D computer models.
gamete. Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
In animals, gametes are produced in male and female gonads. Sperm are motile and have a long, tail-like projection called a flagellum. Ova however, are non-motile and relatively large in comparison to the male gamete. Gametes are produced by a type of cell division called meiosis.They are haploid, meaning that they contain only one set of chromosomes. When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote.The zygote is diploid and contains two sets of chromosomes.efinition: Gametes are reproductive cells (sex cells) that unite during sexual reproduction to form a new cell called a zygote. Male gametes are sperm and female gametes are ova (eggs). In seed bearing plants, p ollen is the male sperm producing gametophyte.
