Cell — The Unit of Life — NEET Biology

Cell — The Unit of Life builds the foundation for most of Class 11 and 12 Biology. It covers the cell theory, the differences between prokaryotic and eukaryotic cells, the cell envelope, and every major organelle from the endomembrane system to mitochondria, plastids, ribosomes and the cytoskeleton. Questions are heavily structure-and-function based.
