Introduction
Scientists estimate that there are more than 300,000 different species of plants on Earth. These plants are very diverse. Take a moment to reflect on some of the weird plants you know about. Did you think of the Venus Flytrap, that digests insects? What about the Touch-Me-Not, which will fold up its leaves to get away from you if you touch it? Did you remember the Corpse Flower, whose large blossom smells like rotting flesh? [include photos and caption of all 3 types of plants] The truth is that plants have a unique ability to adapt to their surroundings. No matter how different plants may appear, they all have the same basic systems and structures. This chapter will examine the way plants work, and the different structures they use to grow and reproduce. Once we understand the plant parts, we will examine some of the ways plant parts work together to support life in the plant. Finally, we will also examine the way plants are classified, and identify plants based on their characteristics.
Plant Structure
Just like all animals have organs that make their bodies work, all plants have structures to carry out their life functions. Like the organs in animals, plant parts are composed of specialized tissues. Tissues combine to make up the basic plant parts. In plants, there are three main types of tissue, shown in Figure XX. These tissues function to give the plant its shape and provide structure. The three types of tissue are: epidermal tissue, ground tissue, and vascular tissue.
Epidermal tissue is the outside covering of a plant. It works just like the skin of an animal to protect internal parts. Because keeping water inside is so important to plants, one of the biggest functions of the epidermal tissue ...

...ray flowers only are dandelions, chicory, and endive. Disk flowers are wider, flat flowers with large stigmas. Some plants that have disk only composite flowers are thistles and burdock. Combination flowers have ray flowers on the edges and disc flowers in the center. Any flower that has an “eye” like sunflowers, daisies, chrysanthemums, or asters is considered a combination composite flower.
