The spirals could go both clock-wise and counter-clock- wise. The number of spirals running in the two directions is known as the Fi-

Plant Diversity I: How Plants Colonized Land Chapter 29 Overview: The Greening of Earth For more than the first 3 billion years of Earth?s history, the terrestrial surface was lifeless Cyanobacteria likely existed on land 1.2 billion years ago Around 500 million years ago, small plants, fungi, and animals emerged on land ? 2011 Pearson Education, Inc. Since colonizing land, plants have diversified into roughly 290,000 living species Land plants are defined as having terrestrial ancestors, even though some are now aquatic Land plants do not include photosynthetic protists (algae) Plants supply oxygen and are the ultimate source of most food eaten by land animals ? 2011 Pearson Education, Inc.

Biology 225: Chapter 35 Q: What are the two systems of a plant and what are they responsible for? A: The Root System (roots) is responsible for absorbing water and minerals from the ground whereas the shoot system (the stems and leaves) is responsible for obtaining light and carbon dioxide from above the ground. Both systems cannot live without the other; the roots require sugar produced by photosynthesis which comes from the shoot system and the shoots require the water and minerals absorbed by the root system for survival. Q: What is the difference between an Angiosperm and a Gymnosperm? A: Vascular Plants with Seeds Gymnosperms Angiosperms

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.

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.
