Word: Blastosphere
Part of Speech: Noun
Definition: The blastosphere is an early stage of an embryo. It forms after a fertilized egg (or ovum) divides into many cells. At this stage, the embryo looks like a liquid-filled sphere made up of a single layer of cells. This is an important stage because about eight days after fertilization, the blastosphere attaches to the wall of the uterus, which is necessary for pregnancy.
Usage Instructions: You can use the word "blastosphere" when discussing biology, especially topics related to embryology, reproduction, or developmental biology. It's a technical term, so it is mostly used in scientific contexts.
Example Sentence: "After fertilization, the ovum undergoes several divisions, leading to the formation of the blastosphere, which will eventually implant in the uterus."
Advanced Usage: In more advanced discussions, you might encounter terms like "blastocyst," which refers to a later stage of development that includes the blastosphere but also has additional structures that will develop into the placenta and other tissues.
