The 7 Themes of Biology
The science of Biology is unified through _ themes.
Notice that an organism needs to exhibit each of these themes to be considered
Plants are able to carry out the process of photosynthesis because of the ability of pigments

Muscles are organs that transfer energy in ATP to energy in movement. To
do this, they need a supply of food and oxygen, and a way to remove the carbon
dioxide produced as a waste product. The b

4. Use a penny to extract the pigments from the various leaf cells. Place a small section of leaf on the top
of the pencil line. Use the ribbed edge of the coin to crush the leaf cells.
