1 Plant Classification

2 Characteristics: 1. Live in MOIST environments WHY? 2. Absorb WATER and NUTRIENTS from their environment NO vascular tissue! (thin cell walls)

3

4 Examples: 1. 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

6 1. Liverworts Found on Moist Rock and Soil beside streams

7

8 Examples: 1. Hornworts Found in Moist Soils

9 Drawing: Label:Sporophyte Capsule Stalk Gametophyte Stemlike structure Leaflike structure Rhizoids

10

11 Characteristics: 1. Have vascular tissue- system of tubelike structures inside a plant that water, minerals, and food move through 2. Do NOT produce seed-reproduce with spores 3. Live in moist surroundings so sperm can swim to eggs

12 Examples: 1. Ferns Size range is small to 5 meters tall! Fronds are FERN LEAVES

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

14 Examples: 1. Club Mosses Grow on moist woodlands near streams

15

16 Examples: 1. Horsetails Steams are jointed

17 Drawing: Label:Frond Spores Stem Roots

18

19 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 Characteristics: 1. Seed plant that produce Naked Seeds 2. Have needle-like or scale-like leaves and deep growing roots

21 Examples: 1. Cycads- palm trees with cones 2. Conifers- Cone bearing plants; aka Evergreens because they keep their leaves year-round 3. Ginkgoes- Ginkgo biloba 4. Gnetophytes- live in hot desert and tropical rainforest

22 Look like Palm trees with cones

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

24 Only ONE species: Ginkgo biloba

25 Live in hot deserts and tropical rainforests

26 Use POLLEN and SEEDS to reproduce!

27

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

29 1. What are some ways that seeds are dispersed? 2. What are the 3 parts of a seed?

30 Characteristics: 1. Produce flowers 2. Seeds are enclosed in fruits

31 Characteristics: 1. FLOWER Reproductive structure of an angiosperm

32 Characteristics: 1. FRUIT Ripened ovary and other structures that enclose one or more seeds (Fruit Development) Dandelion (http://www.youtube.com/watch?v=UQ_QqtXoyQw)http://www.youtube.com/watch?v=UQ_QqtXoyQw
