Mitochondria: Tiny powerhouses of the cell, these double membrane-bound organelles transform food energy into ATP (adesnosine-5’- triphosphate), an all-purpose cellular energy nucleotide, analogous to a rechargeable battery, that can be used for work within the cell.
Cytoplasm: The contents of the cell, between the nucleus and plasma membrane, consist of a gel-like fluid in which the organelles are suspended.

Cytoskeleton: This network of filaments and tubules spans the interior of the cell. The cytoskeleton provides support, anchors organelles, and helps with transport of materials within the cell.
Centrosomes: In plants cells, the centrosome does not contain centrioles like in animal cells, but does function to build microtubules (a component of the cytoskeleton) and is called the microtubule organizing center.
