Chapter 35 Class Notes – Plant Structure, Growth, and Development – Page 1 Max Sauberman AP Biology – Mr. Schilp Chapter 35 Plant Structure, Growth, and Development The Plant Body: The plant body has a hierarchy of organs, tissues, and cells. Plants, like multicellular animals, have organs composed of different tissues, which are in turn composed of cells. Mesophyll tissue and bundle-sheath tissue are two kinds of plant tissue that we’ve seen when discussing photosynthesis. Roots, Stems, and Leaves: Basic morphology of vascular plants reflects their evolution as organisms that draw nutrients from below- ground and above-ground. Just like the blades, holdfasts, and stipes of seaweed, plants have roots, stems, and leaves. These are the three basic organs that have evolved, and they are organized into a root system and a shoot system. Roots go down and shoots go up. Flowering Plant: The plant body is divided into a root system and a shoot system, connected by vascular tissue that is continuous throughout the plant. Its reproductive shoot is the flower. The node is where things branch off.
