Nucleus
The Nucleus is a cell's control center. It has all of the genetic coding that makes your eyes brown for example.
Mitochondria
The Mitochondria are the powerhouses of the cell. They turn food into energy and are classified as organelles or systems inside a cell. The amount of Mitochondria in a cell varies and they can also be found in both plant and animal cells.
Cytoplasm
Cytoplasm is the insides of the cell and protects the more important parts, like the nucleus.
Plant cells are different than animal cells, they are more organized, having cell walls and an extra function.
Cell Walls
These walls seperate plant cells, it's fairly self explanatory.
Chloroplasts
Chloroplasts make the plant appears green.
