Here's a few connections I can make for you:
The cell membrane is what contains everything in the cell. Akin to the skin on humans.
The cytoplasm contains all the cell substances outside of the nucleus.
The nucleus is the control center of the cell. Inside, are the chromosomes which store DNA. The nucleus is surrounded by the nuclear membrane.
The mitochondria is the powerhouse of the cell. It produces energy also known as ATP.
Ribosomes are found attached to the endoplasmic reticulum. Ribosomes are responsible for protein synthesis.
