AP Biology Quizzes & Trivia

Protostomes are a clade of animals that undergo protostomy during their embryonic development and their blastopore becomes the mouth. The protostomes, together with the Deuterostomes and the Xenacoelomorpha, make up a major group of animals called the Bilateria. See how much you know about Protostomes by taking up the quiz below.
