Unit 2 notes from Mr. W.

• The tutorials and student learning guides below align with the learning objectives in Unit 2 in the College Board’s 2025 Course and Exam Description.
• I’ve reordered the College Board’s sequence into one that, to my view, is more logical and more pedagogically sound. Cell structure and function comes first, followed by membrane structure and function.
