Question

Quizplus · Accepted Answer

The body plan consisting of repeating segments, which are modified during development into structures such as vertebrae, ribs, and muscles, relies on the modification of early developmental structures called somites. Somites are blocks of mesodermal cells that form on either side of the neural tube in the developing embryo. They later differentiate into various structures, including muscles, bones, and other tissues. Therefore, the best choice for this question is D) somites.
