Below is a list of organelles that are commonly found in eukaryotic cells.
Organelle: Function
Nucleus: The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.
Mitochondria: Make energy out of food
Ribosomes: Make protein
Golgi Apparatus: Make, process and package proteins
Lysosome: Contains digestive enzymes to help break food down
Endoplasmic Reticulum: Called the "intracellular highway" because it is for transporting all sorts of items around the cell.
Vacuole: Used for storage, vacuoles usually contain water or food. (Are you are thirsty? Perhaps your vacuoles need some water!)
Plant cells also have:
Chloroplasts: Use sunlight to create food by photosynthesis
Cell Wall: For support
