2.10 Origins of Cell Compartmentalization
In short
You are expected to understand the evolutionary origins of cell compartmentalization, specifically focusing on the endosymbiotic theory. You must know that membrane-bound organelles like mitochondria and chloroplasts evolved from once free-living prokaryotes. The depth requires recognizing that while prokaryotes generally lack internal membrane-bound organelles, they do possess internal regions with specialized structures and functions.

What else do you need to know about Origins of Cell Compartmentalization?
Furthermore, you must understand that eukaryotic cells utilize internal membranes to partition the cell into specialized regions. There are no explicit exclusions listed for this topic, so the focus remains strictly on these evolutionary relationships and structural differences.
How is Origins of Cell Compartmentalization tested on the exam?
This topic is frequently assessed using the science practice of Argumentation (Skill 6.B). You may be asked to support a claim with evidence from biological principles, concepts, processes, and data regarding the origin of eukaryotic cells. Questions may require you to explain the relationships between the structure and function of organelles on the subcellular and cellular levels, and to defend the endosymbiotic origin of eukaryotic cells.
