Eukaryote

   
A eukaryote is an organism whose cells contain complex structures inside the membranes. Any member of a group of organisms that contains all plants and animals apart form bacteria and blue-green algae. Their cells possess a membrane-bound nucleus containing the genetic material. Both animals and plants are eukaryotes (meaning their cells have nuclei to hold their DNA instead of letting it just float around anywhere).

Mitochondria

In biology, mitochondria (plural) are the parts of a cell which are responsible for providing the cell with energy; The powerhouse of the cell.

Sink introduced me to this word by describing her 13 year old as ‘mighty mitochondria’ – what a great description for a bundle of energy!
