a process fusing the nuclei of two gametes sperm cell cell produced by meiosis diploid cell resulting from fertilization

Explanation:

• Zygote: A diploid cell resulting from fertilization. In humans, it is formed when a sperm (male gamete) fertilizes an egg (female gamete). It has a full set of chromosomes (46 in humans) and is the starting point for the development of a new individual.
• Gamete: A cell produced by meiosis. In humans, examples include the sperm cell (male gamete) and the egg cell (female gamete). Gametes are haploid (contain half the number of chromosomes of a normal body cell, 23 in humans) and are involved in sexual reproduction.
• Fertilization: A process fusing the nuclei of two gametes. In humans, it is the union of the sperm and the egg. During this process, the genetic material from the sperm and the egg combines, restoring the diploid chromosome number in the resulting zygote.

Answer:

• Zygote: diploid cell resulting from fertilization
• Gamete: cell produced by meiosis (e.g., sperm cell)
• Fertilization: a process fusing the nuclei of two gametes
