Video transcript: Inside a Eukaryotic Cell: What Each Organelle Does

Did you know? Eukaryotic cells contain a variety of specialized organelles each performing distinct functions that keep the cell alive and functioning. The nucleus houses the cell's DNA and controls gene expression. Endoplasmic reticulum, or ER, comes in rough and smooth forms, synthesizing proteins and lipids respectively. The Golgi apparatus modifies, sorts, and ships these molecules, while mitochondria generate energy through cellular respiration. Lysosomes and peroxisomes break down waste and detoxify harmful substances, while ribosomes assemble proteins. Now you know!
