Ten Parts, Ten Shapes, Ten Jobs

You'll learnhow each organelle's shape is the reason it can do its job.

Zoom in on a cell and it resolves into ten parts, almost every one a job boxed behind its own membrane. Read each part’s shape and its job falls out — then meet the one part with no membrane at all, and the cell with no rooms that is still nowhere near empty. Twelve short steps; press Next for each one.

ten parts · one promise · the shape is the job
