Development
This organelle has a "rough" part with ribosomes attached.
Endoplasmic Reticulum or ER
Small vesicles containing digestive enzymes to break down waste; the garbage disposal of the cell

When you exercise, you develop more of this organelle in your muscle cells

All living things obtain and use this to carry out life processes.
Energy
