Here's a breakdown:
* Internal Morphology: Refers to the organism's internal structure, including its organs, tissues, and cells. Think of things like the arrangement of bones in a skeleton, the structure of the heart, or the arrangement of different cell types in a tissue.
* External Morphology: Refers to the organism's outward appearance, including its shape, size, color, and external features. This could involve things like the number of limbs, the shape of the head, or the presence of specific markings or patterns.
Together, internal and external morphology provide a complete picture of an organism's physical structure.
