The three structures found in plant cells that aren't found in animal cells are the cell wall, chloroplast, and the large central vacuole. The cell wall is a hard outer covering that allows plant cells to keep their shape. Chloroplast contain the pigment known as chlorophyll and allow plants to undergo photosynthesis. Finally, the large central vacuole is there to allow plants to store lots of water.
The gradual abundance of oxygen (by product of photosynthesis) made it possible for aerobic organisms to grow more and evolve.
Hope that helps!
