A thorough knowledge of plant structures is essential for Horticulturalists.  This lab is designed to help the student become familiar with various plant structures.  Plants can be divided into three vegetative organs: 1) stems, 2) roots and 3) leaves and one reproductive organ, the flower.  Each of these organs has a typical structure, and in addition, each may be modified into specialized structures.  Vegetables are structures that develop from one of the the three vegetative organs.  Fruits develop from the ovary of the flower.  Seeds develop only from the ovule, and occur alone only when the fruit wall has been removed.     The purpose of this lab: 1) To recognize and identify the types of roots and root modifications based on origin, structure or function.  2) To recognize and identify the typical parts of leaves, leaf types and leaf modifications.  3) To recognize and identify the typical parts of stems and stem modifications. 4) To recognize and identify the parts of flowers.  5) To recognize and identify the parts and types of fruits and fruit modifications.
