These beautiful flowers contain endosperm. The endosperm tissue surrounds and nourishes the embryo in the angiosperm seed.

This bird is an endotherm. Endotherms are organisms that have the ability to generate their own heat to maintain body temperature.

This picture of my hand is an example of epithelial tissue. Epithelial tissue covers the entire surface of the body, and it is made up of closely packed cells in one or more layers.

This flower is an example of the stigma and style of carpel. The stigma and style are attatched to the ovary, which is at the base of the flower. The style is a tubular structure that extends from the ovary. On top of the style is the stigma, which is a surface receptive to pollen.
