Cell Structure and Function Overview

This video by Melanie King from The Absolute Recap reviews Unit 2 of AP Biology, focusing on cell structure and function. It covers macromolecules, membrane structure, organelles, cellular transport, water potential, and the differences between prokaryotic and eukaryotic cells. The video emphasizes the importance of understanding these concepts for the AP Biology exam and provides resources for further practice.
