2.1 Cell Structure and Function: revision map
The subtopic in the middle and four tasks round it: label a diagram, complete two tables and fill 14 gaps. Every box rests on a learning objective of the topic in the AP Biology course and exam description. Type into the blanks and check them, or print it on A4, Letter or A3 with an answer key.

2.1.AStructure fits function
A cell's organelles do different jobs, and the number of each reflects what the cell does. A muscle cell, which uses a lot of ATP, has many , and a gland cell that exports protein has a large rough ER and Golgi apparatus. Every cell, prokaryotic or eukaryotic, has a plasma membrane, cytoplasm, DNA and , which is evidence that they share an ancestor.
