Answer 1

Answer:

The new is called zygote from seed by doing the process of pollination in plants there is no Zygote in human being

Answer 2

1. Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

2. In the human reproductive process, two kinds of sex cells, or gametes (pronounced: GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (pronounced: ZYE-goat).

3.The sperm nucleus then fuses with the ovum, enabling fusion of their genetic material. When the sperm enters the vitelline space, receptors on the sperm head called Izumo1 bind to Juno on the oocyte membrane.
