The sun is like the nucleus of a cell because it is the source of power for everything in the solar system just like the nucleus is the source of power for every process in the cell.

An asteroid belt is like a cell membrane because it keeps most things out while other stuff gets into the solar system. Just like how the cell membrane controls what goes in or comes out of the cell.

Gravity is like a cell wall because it keeps everything in place and everything in orbit

An orbit is like an endoplasmic reticulum(ER) because the orbit is how all planets stay on their own path around the sun. The ER are the passages for proteins to move through the cell.

A rocket is like the Golgi apparatus because it carries astronauts to different areas of the solar system.

The sun is also like the mitochondria because the sun supplies all the power to the solar system.

The solar system itself is like the vacuoles because the waste that is in the solar system has nowhere to go.

Just like the nucleus and the mitochondria, the sun is also like the ribosome because the sun produces what the solar system needs.

Cell wall-outermost covering Chloroplasts-photosynthesis Usually square Usually one large vacuole Do cell respiration Are eukaryotes (have a nucleus) Cytoskeleton-inside cell No chloroplasts Can be any shape Many small vacuoles
