Vascular Tissue and Transport VASCULAR TISSUE & TRANSPORT Plants rely on specialized tissue, called vascular tissue, to transport water, nutrients, and the products of photosynthesis around the plant. The two types of vascular tissue are: xylem (zy-lum) phloem Water Transport Xylem - Transports water from the roots up to the rest of the plant in one way flow. Tracheids - Hollow cell in xylem with thick cell walls that resist turgor pressure Water Transport Water rises through the thin tubes by a process called capillary action (cohesion of water molecules and adhesion to solid surface). The thinner the tube, the higher the water will rise.

Classification Multicellular Eukaryote Have cell walls made of cellulose Carry out photosynthesis AND respiration Most are autotrophs A few are parasites (live on living organisms) or saprobes (live on dead organisms) Store energy as starch (carbohydrates) Sunlight Water Minerals Gas Exchange (CO2 in: O2 and some CO2 out) Transport of water and nutrients throughout the plant body Remember Photosynthesis: 6H2O + 6CO2 ? C6H12O6 + 6O2 (water + carbon dioxide + sunlight ? glucose + oxygen) Plants life cycles have two alternating phases known as alternation of generations: A diploid (2N) phase known as the sporophyte (spore producing plant). A haploid (N) phase known as the gametophyte (gamete producing plant)

Chris Schink Biology Vocab Chapter 29 Parenchyma- In higher plants, the fundamental tissue that is composed of thin walled living cells that function in photosynthesis and storage. Collenchyma- A group of elongated, thick walled plant cells that support the growth of leaves and stems. Sclerenchyma- A type of plant tissue composed of cells that have thickened secondary walls that function in plant support. Epidermis- The outer layer of cells of a plant or animal. Cuticle- A waxy or fatty watertight layer on the external wall of epidermal cells. Tracheid- A thick-walled cylindrical cell with tapered ends that is found in xylem and that provides support and conducts water and nutrients. Pit- In plants, the thin, porous areas of a tracheid cell wall.

The Nervous System Function: The function of the nervous system is to control and coordinate functions throughout the body and respond to external and internal stimuli. The nervous system is divided into 2 parts the PNS (peripheral nervous system) and the CNS (central nervous system), and is in control of both. Nerve signals are transmitted through these systems. Interdependence: The nervous system relies on the muscular system to work properly. Organism Comparison: A flatworm?s nervous system is simpler compared to humans. It has nerve cords that control its actions. The Skeletal System

Mosses and liverworts are traditionally classified together in the Division Bryophyta on the basis of their sharing: •a similar life cycle (alternation of generations) •similar reproductive organs (antheridia and archegonia) •lack of vascular tissue (xylem and phloem) Some 23,000 species of living mosses and liverworts have been identified. These are small, fairly simple, plants usually found in moist locations. •Liverworts have a thin, leathery body that grows flat on moist soil or, in some cases, the surface of still water. The photo (courtesy of William C. Steere and AIBS Bulletin) is of a common liverwort, Ricciocarpus natans. •Mosses have an erect shoot bearing tiny leaflike structures arranged in spirals.

J I TECHNO-ECONOMIC EVALUATION OF WASTE LUBE OIL RE-REFINING IN SAUDI ARABIA Mohammad Farhat Ali, Abdullah J. Hamdan and Faizur Rahman DEPARTMENT OF CHEMISTRY Kine Fahd Universitv of Petroleum & Minerals " Dhahran: Saudi Arabia Keywords: Waste Lube Oil. Re-refining, Economics INTRODUCTION Abut 80 million gallons of automotive lubricating oils are sold in Saudi Arabia. Much of this oil, after use, is actually contributing to the increased pollution of land because of indiscriminate dumping. Any scheme of secondary use of the waste lube oils would be of interest both for conservation of energy resources and for protection of environment. This paper discusses the secondary use for the used automotive lubricating oils. Process technology
