I need a list of every organelle in a cell and what they do.
ex. Cytoplasm | The interior liquid of the cell. Helps to hold organelles in place

Assuming this is basic high school level. Plant organelles and animal organelles are different. So here's both.
Mitochondria: Powerhouse of the cell, produces energy
Choroplasts: Produces energy in plants through photosynthesis- using light energy.
Endoplasmic reticulum (smooth and rough) - Make and export proteins and fats (lipids)
Lysosome- Contains enzymes, breaks down proteins
Cell membrane- Allows necessary chemicals in and out of the cell.
Cell wall: Holds the contents of a cell in. Expands to hold water. Only in plants.
Centrosome: Helps with the cell cycle
Vacuole: Storage space that holds water and solutions.
Nucleus: contains genetic material -DNA- and gives instructions to the cell
Golgi apparatus: Packages proteins intro membrane bound vesicles.
Ribosome: Making proteins (synthesis)
Next time, be a little more specific please!
