11. Eukaryote

Eukaryote are cells contained by complex organisms. These cells are the building blocks of an organism, some containing millions upon millions to small for the naked eye to see. Eukaryote cells have a membrane surrounding them, along with many organelles that have their own job to carry out in order to keep the cell alive.
In this picture, we see a collection of flowers all made up of the complex eukaryote cells.
