1 Plant Classification PLANTS!

2 Nonvascular Plants Characteristics: Live in MOIST environments
WHY? Absorb WATER and NUTRIENTS from their environment NO vascular tissue! (thin cell walls)

3 Nonvascular: MOSSES

4 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

5 Nonvascular: Liverworts

6 Nonvascular Plants Liverworts
Found on Moist Rock and Soil beside streams

7 Nonvascular: Hornworts

8 Nonvascular Plants Examples: Hornworts Found in Moist Soils

9 Nonvascular Plants A Moss Plant (Pg. 123)
Drawing: Label: Sporophyte Capsule Stalk Gametophyte Stemlike structure Leaflike structure Rhizoids

10 Sphagnum Moss turns to Peat

11 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

12 Seedless Vascular Plants
Examples: Ferns Size range is small to 5 meters tall! Fronds are FERN LEAVES

13 Club Mosses How are club mosses different from “true” mosses?

14 Seedless Vascular Plants
Examples: Club Mosses Grow on moist woodlands near streams

15 Horsetails

16 Seedless Vascular Plants
Examples: Horsetails Steams are jointed

17 Seedless Vascular Plants FERN: Page 128
Drawing: Label: Frond Spores Stem Roots

18 Spores on a Fern Frond

19 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

20 Gymnosperms Characteristics: Seed plant that produce Naked Seeds
Have needle-like or scale-like leaves and deep growing roots

21 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

22 Cycads Look like Palm trees with cones

23 Conifers Cone Bearing Plants Evergreens (keep leaves year-round)

24 Ginkgoes Only ONE species: Ginkgo biloba

25 Gnetophytes Live in hot deserts and tropical rainforests

26 Gymnosperm Life Cycle Use POLLEN and SEEDS to reproduce!

27 Seeds- 3 main parts

28 Seed Dispersal The scattering of seeds so they are away from the parent plant.

29 Seed Dispersal Video What are some ways that seeds are dispersed?
What are the 3 parts of a seed?

30 Angiosperms Characteristics: Produce flowers
Seeds are enclosed in fruits

31 Angiosperms Characteristics: FLOWER
Reproductive structure of an angiosperm

32 Angiosperms Characteristics: FRUIT
Ripened ovary and other structures that enclose one or more seeds (Fruit Development) Dandelion (http://www.youtube.com/watch?v=UQ_QqtXoyQw)

33 Angiosperms Plant Part MONOCOT DICOT Seed One cotyledon 2 cotyledons
Leaf Parallel veins Branching veins Stem Bundles of vascular tissue scattered Bundles of vascular tissue arranged in a ring Flower Parts in 3 Parts in 4 or 5 Example Tulip, Grass, Wheat, Corn Roses, Violets, Dandelions

34 Monocots vs. Dicots

35 Angiosperms- MONOCOTS
Tulips Grass Wheat Corn

36 Angiosperms- DICOTS Roses Violets Dandelions

37 Pollination

38

39 Angiosperm Life Cycle

40 Drawings POLLEN OVARY (Label OVULE) 100x
