What you'll learn

Cells, discovered by Robert Hooke in 1665, are the basic units of life — either simple prokaryotes or complex eukaryotes with a nucleus and organelles. The cell membrane controls entry and exit, while organelles like the nucleus, mitochondria, and ribosomes drive vital functions, with size and shape shaping efficiency and complexity.
