Flashcard facts and information about the parts of the cell

Biology Bits stories are a great way for you to learn about biology a little bit at a time. We’ve broken down information into pieces that are very tiny—bite-sized biology cards. Cutting out the cards will let you organize them however you want, or use them as flashcards while you read.

This set of bits will teach you about the tiny world on which life depends: the parts inside a cell. To learn more about the science behind your cells, visit Building Blocks of Life - Parts of the Cell.
