What does the term 'sketch' refer to in a biological context?

In a biological context, the term 'sketch' refers specifically to a brief, labeled diagram or graph. This type of representation highlights key features and information succinctly, allowing for a quick understanding of a concept without the need for intricate detail. In biology, sketches can illustrate processes, structures, or relationships in a straightforward manner, making it easier for students to convey essential information efficiently.

The focus on brevity and clarity is what distinguishes a sketch from other forms of representation, such as detailed drawings, which require more precision and complexity, or three-dimensional models that provide a tangible, spatial understanding of structures but are not considered sketches. A diagrammatic representation might fall into a similar category but does not necessarily imply the brevity and labeling that characterize a sketch specifically.
