Today’s Agenda Introduction Lesson Discussion Quiz Welcome to class!!
Introduction: Daniel L. Barr • Hometown; Pierceton • Age; 23, oldest of three • Major; Life Science Education • School; Homeschooled K-12 • College; Sophomore at Manchester College after 2 yrs at Ivy Tech Community College, Warsaw • Favorite Sports Teams; NFC – Chicago Bears AFC – Pittsburgh Steelers MLB – Chicago Cubs NCAA D1 Football – Michigan Wolverines NCAA D1 Basketball – Illinois and Butler
Taxonomy • Definition: The naming and grouping of organisms. i.e. plants • Levels of Classification; Domain, Kingdom, Phylum, Class, Order, Family Genus, Species. • Plants fall under; Domain – Eukarya, Kingdom – Plantae
First Classification Level Non-vascular (Bryophytes) Plants and Vascular (Tracheophytes) Plants
Bryophytes • No vascular tissue • Found in only in wet areas • Most prominent life stage is the haploid (1n) gametophyte stage • Fossils date back to the Devonian Period, 400 million years ago. • Peat Moss covers 2% of all land on Earth, an area equal to the land area of the US!
Tracheophytes, the Vascular Plants. Fossils date back to the Silurian Period
Tracheophytes • Over 290,000 named species. • The diploid (2n) sporophyte stage is most prominent. • Contain Vascular Tissue, Xylem and Phloem, arranged in vascular bundles. • Lignin, a supportive material, an important component of wood.
Sub-classification Woody and Herbaceous Plants
Tracheophytes;Both Seeded and seedless plants can be either woody or herbaceous Woody Herbaceous Daffodils Sequoia
Second Classification Level Seedless Vascular Plants and Seeded Vascular Plants
Seedless Plants Reproduces through spores Fossils of seedless plants date to the Carboniferous Period, 345-280 million years ago
Divisions of Seedless Plants Pterophytes (Ferns) Lycophytes (Club Mosses) Equisetophytes (Horsetails)
Equisetophytes (Horsetails) • Contains bits of silica, giving them a rough feel • Has true roots • Grows in moist areas
Lycophytes (Club Mosses) • True roots, stems, and leaves • A simple arrangement of xylem and phloem • All Lycophytes have spore producing structures called strobili, the clubs on club mosses.
Pterophytes (Ferns) • There are 13,000 named species today • Some ferns can grow to be tree sized • Some fronds, called sporophylls, have spore producing structures call sporangia on their undersides
First Classification Level of Seeded Plants Naked Seed (Gymnosperms) Plants and Flowering (Angiosperms) Plants; Both Gymnosperms & Angiosperms can be either woody or herbaceous
Divisions of Gymnosperms (Plants with Naked Seeds)First Appears in the Permian Gnetophytes Cycadophyta Ginkgophyta Coniferophyta
Cycadophyta • Large leafed plants that look like short palm trees • The Sago Palm is used as an ornamental • Seeds are born on large cones on top of the plant • A variety of Australian cycad can have cones up to 1 meter long and weigh up to 90 pounds.
Ginkgophyta • AKA the Maidenhair Tree, is a native of China and Japan • A living fossil • Extinct in the wild • Can grow up to 40 meters tall • Male pollen producing cones are small • Females keep fleshy and smelly seeds at the ends of short stalks.
Gnetophyta (Welwitschia) • Three genera • Some have large, leathery leaves. • Continuous growth • Reproductive scales are clustered into cones
Coniferophyta • Includes Pines, Firs, Spruces, and Cedars • Named for their distinctive cones • Modified leaves; either needles (Pines) or thin, scaly leaves (Cedars) • Includes both the tallest plants, California Redwoods, and the oldest plants, Bristlecone Pines, in the world. Northern White Cedar
Angiosperms, AKA Anthophyta. The Flowering Plants • Fossils first appear in the Cretaceous • There are some 275,000 known species today • All have flowers and fruits • Many Angiosperm seeds have endosperm
Angiosperms (Flowering Plants), AKA Anthophyta Monocots Dicots, AKA Eudicots
Angiosperms Monocots Dicots Wheat Onions Sugar Cane Lilies Soy Beans Oranges Oaks Roses
Question 1 • Pines belong to which division of the plant kingdom? • (A) Bryophytes • (B) Angiosperms • (C) Coniferophyta • (D) Lycophyta
Question 2 • If I am a plant that has vascular tissue, silica in my cells, and reproduces with spores, what division do I belong to? • (A) Angiosperms • (B) Eqisetophyta • (C) Bryophyta • (D) Monocot
Question 3 True or False. The prominent stage of a Bryophyte is the 1n gametophyte
Question 4 • What division of plants does the tallest plant in the world belong to? • (A) Anthophyta • (B) Pterophyta • (C) Lycophyta • (D) Coniferophyta
Question 5 • What is the job of Xylem? • (A)To carry juices throughout the plant • (B) To carry water up from the roots to the rest of the plant • (C) To carry sugars down from the leaves • (D) To provide a clear note when tuning a xylophone
Question 6 • In the picture, what division of plants do these cones belong to? • (A) Coniferophyta • (B) Ginkgophyta • (C) Pterophyta • (D) Cycadophyta
Question 7 • True or False. Club Mosses lack vascular tissue.
Question 8 • What is the study of the naming of and organizing of organisms? • (A) Taxidermy • (B) Choreography • (C) Taxonomy • (D) Botany
Question 9, short answer • What is the difference between a dicot and a monocot?
Question 10, short answer • List from highest order to lowest order the different levels of the cladogram from question 8.
