What is the primary function of the notochord in chordates?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Support.
The primary function of the notochord in chordates is support.
-
The notochord is a flexible, rod-like structure made of cells and supportive tissues that runs along the dorsal side of the body in all chordates at some stage of development.
-
It provides structural support, helping the body maintain its shape and serving as a skeletal axis around which muscles can attach.
-
In vertebrates, the notochord is present during embryonic development and is later replaced by the vertebral column, but it still contributes to body flexibility and movement.
