It provides energy for the cell to build, repair, and reproduce. Cells needing more energy have more mitochondria.
A cellular organelle is a structure in the cell that performs a specific function.
Nucleus - stores cell's DNA; DNA replication occurs here
Ribosome - produce protein; "factories" of the cell
Mitochondria - breaks down food for energy to be used by the cell; "powerhouse" of the cell
Vacuole - store materials such as food, water, sugar, minerals, and waste products
Endoplasmic reticulum - carry materials throughout the cell; "transport system"
