Plant Classification PLANTS!
Nonvascular Plants Characteristics: Live in MOIST environments WHY? Absorb WATER and NUTRIENTS from their environment NO vascular tissue! (thin cell walls)
Nonvascular Plants Examples: Mosses Gametophyte is green and fuzzy Sporophyte is long and slender with capsule at the end Peat moss is used in agriculture and gardening Peat is used as fuel
Nonvascular Plants Liverworts Found on Moist Rock and Soil beside streams
Nonvascular Plants Examples: Hornworts Found in Moist Soils
Nonvascular PlantsA Moss Plant (Pg. 123) Drawing: Label: Sporophyte Capsule Stalk Gametophyte Stemlike structure Leaflike structure Rhizoids
Vascular Seedless Plants Characteristics: Have vascular tissue- system of tubelike structures inside a plant that water, minerals, and food move through Do NOT produce seed-reproduce with spores Live in moist surroundings so sperm can swim to eggs
Seedless Vascular Plants Examples: Ferns Size range is small to 5 meters tall! Fronds are FERN LEAVES
Club Mosses How are club mosses different from “true” mosses?
Seedless Vascular Plants Examples: Club Mosses Grow on moist woodlands near streams
Seedless Vascular Plants Examples: Horsetails Steams are jointed
Seedless Vascular PlantsFERN: Page 128 Drawing: Label: Frond Spores Stem Roots
Ticket Out the Door On a piece of paper draw the Venn Diagram below. Include: 2 Similarities between Nonvascular and Seedless Vascular Plants 2 Differences between Nonvascular and Seedless Vascular Plants Nonvascular Seedless Vascular 1. 1. 1. 2. 2. 2.
Gymnosperms Characteristics: Seed plant that produce Naked Seeds Have needle-like or scale-like leaves and deep growing roots
Gymnosperms Examples: Cycads- palm trees with cones Conifers- Cone bearing plants; aka Evergreens because they keep their leaves year-round Ginkgoes- Ginkgo biloba Gnetophytes- live in hot desert and tropical rainforest
Cycads Look like Palm trees with cones
Conifers Cone Bearing Plants Evergreens (keep leaves year-round)
Ginkgoes Only ONE species: Ginkgo biloba
Gnetophytes Live in hot deserts and tropical rainforests
Gymnosperm Life Cycle Use POLLEN and SEEDS to reproduce!
Seed Dispersal The scattering of seeds so they are away from the parent plant.
Seed Dispersal Video What are some ways that seeds are dispersed? What are the 3 parts of a seed?
Angiosperms Characteristics: Produce flowers Seeds are enclosed in fruits
Angiosperms Characteristics: FLOWER Reproductive structure of an angiosperm
Angiosperms Characteristics: FRUIT Ripened ovary and other structures that enclose one or more seeds http://www.youtube.com/watch?v=sEwmUbzN_-g (Fruit Development) Dandelion (http://www.youtube.com/watch?v=UQ_QqtXoyQw)
Angiosperms- MONOCOTS Tulips Grass Wheat Corn
Angiosperms- DICOTS Roses Violets Dandelions
