gastrula
This term is a specialized biological descriptor used primarily in embryology and developmental biology. It describes a specific morphological transition where a blastula reorganizes into a multi-layered structure, establishing the body plan of the organism. Because it refers to a precise developmental phase, it is used in a technical, scientific register rather than in general conversation.
In academic writing, the term is often paired with the process of gastrulation. While it refers to the physical entity of the embryo at this stage, it is treated as a countable noun when discussing different species or different stages of development across various embryos.
Meanings
Examples
The blastula transforms into a gastrula through the process of invagination.
Look at this slide to see the distinct layers of the gastrula.
The gastrula stage marks the beginning of tissue differentiation.
Does the gastrula always form a blastopore in this species?
The embryo has now reached the gastrula phase of development.
I wonder if the gastrula will develop normally under these conditions.
The formation of the gastrula is essential for creating the gut.
We are studying how the gastrula organizes the body axis.
