SEXUAL CELL Meaning and
Definition
-
A sexual cell, commonly referred to as a gamete, is a specialized reproductive cell that is involved in sexual reproduction. It is specifically designed for the transmission of genetic material to create new offspring. Sexual cells are found in both plants and animals and come in two different types - sperm cells and egg cells.
Sperm cells, also known as spermatozoa, are the male gametes. These small, motile cells are produced in the testes of male organisms. They are characterized by their streamlined shape and are equipped with a tail-like flagellum that enables them to swim towards the egg cell. Upon fertilization, a sperm cell fuses with an egg cell to form a zygote, which eventually develops into a new individual.
On the other hand, egg cells, or ova, are the female gametes. They are larger in size compared to sperm cells and are immobile. Egg cells are formed within the ovaries and are released during ovulation. They contain stored nutrients to nourish the developing zygote after fertilization.
Sexual cells play a crucial role in sexual reproduction as they carry half of the genetic material from each parent. This genetic diversity contributes to the variability and adaptation of offspring, allowing for evolution and the preservation of species. The fusion of sexual cells is a key step in the process of fertilization, leading to the formation of a new organism.
Common Misspellings for SEXUAL CELL
Etymology of SEXUAL CELL
The term "sexual cell" is primarily derived from the combination of two separate words: "sexual" and "cell".
1. Sexual: The word "sexual" originates from the Latin word "sexus", which means "gender" or "the state of being male or female". It is directly related to the Latin word "secare", meaning "to divide" or "to separate". Over time, the concept of "sexual" evolved to refer to things related to the physical, biological, or psychological differences between male and female organisms, primarily focused on reproduction.
2. Cell: The word "cell" has its roots in the Latin word "cella", meaning "small room" or "storeroom". However, the term took on its modern meaning in biology due to the work of Robert Hooke in the 17th century.
