ZYGOSPERM Meaning and
Definition
-
Zygosperm is a biological term that refers to a type of seed produced by certain plant species. It is a compound word derived from "zygo-", meaning "yoked" or "joined," and "sperm," indicating "seed." The term is commonly used in the context of botany and plant reproduction.
In plant biology, zygosperm specifically describes a type of seed resulting from double fertilization, a unique process in angiosperms (flowering plants). During double fertilization, one sperm cell from the pollen fertilizes the egg to form the embryo, while the other sperm cell fuses with the polar nuclei in the central cell to form the endosperm. This combination of the embryo and endosperm within a seed is characteristic of zygosperms.
Zygosperms typically have a unique structure that differentiates them from other types of seeds. They often possess a zygote, which is the result of the fertilization process, and an endosperm, which is a nutrient-rich tissue that supports the growth and development of the embryo. The zygote and endosperm are enclosed within a protective seed coat.
This term is commonly used in scientific research, particularly in the study of plant growth and reproductive mechanisms. Understanding zygosperms is important for comprehending the life cycle and evolutionary adaptations of flowering plants.

Etymology of ZYGOSPERM
The word "Zygosperm" is a combination of two terms: "zygo" and "sperm".
The term "zygo" is derived from the Greek word "zygón", which means "yolk" or "germ". In biological terminology, "zygo-" is often used to refer to joining or pairing.
The term "sperm" comes from the Greek word "sperma", which means "seed" or "sperm". In biology, "sperm" represents the male reproductive cell that fertilizes the female reproductive cell.
Therefore, "Zygosperm" combines these two concepts. It refers to a type of seed or reproductive cell that results from the union or pairing of male and female reproductive cells.
