ZYGOTE Meaning and
Definition
-
A zygote is a biological term that refers to a single-cell organism resulting from the fertilization of an egg cell by a sperm cell in sexual reproduction. It represents the initial stage of embryonic development and is commonly found in animals and plants. The process of fertilization occurs when a sperm penetrates an egg, leading to the fusion of their genetic material. This fusion creates a genetically unique zygote, which contains the complete set of chromosomes required for the development of a new individual.
The zygote plays a fundamental role in shaping the subsequent stages of embryonic development. It undergoes a series of cell divisions known as mitosis, which allows it to multiply rapidly and form an embryo. During these divisions, the zygote differentiates into specialized cells and tissues that eventually develop into the various organs and systems of the organism. This process is vital for the growth and maturity of living organisms.
The zygote is considered diploid, meaning it possesses two sets of chromosomes, one from each parent. It carries the genetic information from both the father and the mother, determining various traits and characteristics of the offspring. Additionally, the zygote contains all the necessary factors required for the development and differentiation of its cells.
In summary, a zygote represents the earliest stage of embryonic development resulting from the fusion of an egg and a sperm. It contains the genetic material necessary for the growth and development of a new organism.

Common Misspellings for ZYGOTE
Etymology of ZYGOTE
The word "zygote" comes from the Greek word "zygotos", which means "yoked" or "joined together". It is derived from the Greek verb "zeugnynai", meaning "to join or yoke together". The term was first used in embryology by German biologist and philosopher Ernst Haeckel in the late 19th century to describe the fertilized egg, resulting from the fusion of gametes during sexual reproduction.
