GED® Science: The Cell -- Structure & Function (Deep Dive)
A deep dive into the cell, expanding the single 'The Cell' lesson from the GED® Life Science course into a full mini-course. You'll learn the cell theory and how cells were discovered, the difference between bacteria-style (prokaryotic) and plant/animal-style (eukaryotic) cells, what each organelle does, how plant and animal cells differ, how the cell membrane controls what moves in and out, and how cells divide. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.
