Answer:
The mitochondria and chloroplasts are sources of energy for the cell.
Step-by-step explanation:
The mitochondria is the location of aerobic respiration, and chloroplasts the location for photosynthesis.
Cytoplasm acts like a soup holding everything in the cell, and nutrients can be contained within it, however the cell membrane controls what can enter and exit a cell.
The cell wall and mitochondria do not sort and package proteins. This is done by the Golgi Apparatus
The cell wall provides stability and strength to plant cells, enabling them to keep their shape.
