Bio 1305 Exam 4 Fall 2007 Review Chapter 34 1. What plant evidence was used to solve the Lindbergh kidnapping? The wood grain and the rings in the wood 2. What are some differences in monocots and dicots? Monocots: 1 cotyledon, veins in the leaves are parallel, flower petals are in multiples of three, arrangement of the vascular bundles in the stems are scattered Dicots: 2 cotyledons, veins in the leaves are netlike, flower petals are in multiples of fours and fives, arrangement of the vascular bundles in the stems are in a ring 3. What are the 3 tissue systems of plants? Describe the structure and function of each system. Dermal tissue: outer covering of the plant, protects the plant body surface Ground tissue: makes up the rest of the plant, it functions in storage, support, photosynthesis, mechanical support, and the production of digestive and attractive substances Vascular tissue: plant’s plumbing or transport system; its two constituent tissues are the xylem and phloem which distribute materials throughout the plant 4. What are the vegetative (nonreproductive) organs of flowering plants? Roots, stems, and leaves 5. How do plant cells differ from animal cells? Plant cells are different from other eukaryotic cells in having chloroplasts or other plastids, vacuoles, and cellulose-containing cell walls. 6. How do plant cells communicate with other cells? Plasmodesmata 7. What are the 3 types of ground tissues? Parenchyma: store starch or lipids and some carry out photosynthesis and contain numerous chloroplasts, serve as packing material and play a vital role is supporting the stem, thin primary wall Collenchyma: supporting cells thick primary walls, elongated, no secondary cell wall, flexible support, provides support to leaf petioles, nonwoody stems, and growing organs Sclerenchyma: include fibers (provide relatively rigid support in wood and other parts of the plant where they are often organized into bundles ex. Bark of trees) and sclereids (pack together densely as in a nut’s shell or in some seed coats) that provide strength and often do not function until they die, thick secondary cell walls that perform their major function: support 8. What types of cells make up the xylem? Conducting cells called Tracheary elements (include tracheids and vessel elements) which undergo programmed cell death before they assume their function of transporting water and dissolved minerals 9. What is indeterminate and determinate growth? Determinate growth- the growth of the individual and all its parts ceases when the adult state is reached (characteristic of some plant parts such as leaves, flowers and fruits) Indeterminate growth- growth of stems and roots (generated from specific regions of active cell division and cell expansion)
