- 11. Fig. 1.3, p. 4 molecule Atoms joined in chemical bonds. This is a model of a water molecule. The molecules of life are much larger and more complex than water. organ Structural unit of interacting tissues. Flowers are the reproductive organs of many plants. atom Atoms are fundamental units of all substances, living or not. This image shows a model of a single atom. organ system A set of interacting organs. The shoot system of this poppy plant includes its aboveground parts: leaves, flowers, and stems. cell The cell is the smallest unit of life. Some, like this plant cell, live and reproduce as part of a multicelled organism; others do so on their own. tissue Organized array of cells and substances that interact in a collective task. This is epidermal tissue on the outer surface of a flower petal. 1 2 3 4 5 6

- 28. Fig. 1.4b, p. 6 C All of the energy that enters the world of life eventually flows out of it, mainly as heat released back to the environment. Stepped Art Energy, Producers, and Consumers sunlight energy A Producers harvest energy from the environment. Some of that energy flows from producers to consumers. Producers plants and other self-feeding organisms Consumers animals, most fungi, many protists, bacteria B Nutrients that become incorporated into the cells of producers and consumers are eventually released by decomposition. Some cycle back to producers.
