Like all other plants, Echinacea purpurea undergoes the process of photosynthesis in order to produce energy.  This process occurs in the chloroplasts of plant cells and is a critical component to a plant's survival.  The purple coneflower is an autotrophic organism, making photosynthesis its primary source of nutrition.  The process of photosynthesis is when an organism uses energy from the sun to produce sugars.  To learn about another photosynthetic organism, the Northern Maidenhair Fern, click here.

Besides photosynthesis, Echinacea purpurea also absorbs various nutrients and water through its roots where it is transported throughout the plant via specialized cells called xylem and phloem. To learn about the Silver Maple, another organism that contains xylem and phloem, click here.

Besides these two main vascular tissue cells, land plants have adapted over time and developed stomata which are small mechanisms that help regulate the flow of water and different gases in and out of the plant.   The best pH range for this plant is around 6-7 pH.  This allows for the best release of nutrients and gases.  All of the unused nutrients are stored in the form of glucose, preferably cellulose or starch.
