1. GROUPS OF PLANTS

2. NON-VASCULAR PLANTS Do not have a system to transport water and nutrients Get water through diffusion Small- because they cannot move water far Seedless (use spores)

3. Types of non-vascular plants Mosses Grow in moist soil, sides of trees, rocks Leafy stalks Rhizoids are root-like structures that help mosses attach to surfaces Liverworts and Hornworts Small Live in damp places Rhizoids keep them in place

4. VASCULAR PLANTS Have a vascular system to move materials Root and Shoot systems Leaves, Stems (shoot system) and roots (root system) are 3 major organs Leaves- make food, and allow gas exchange (through stomata) Stems- provide support and transport Roots- supply water and minerals, anchor plants, and store extra food

5. Seedless vascular plants Use spores to reproduce Ferns and Whisk Ferns Have roots Have rhizomes to help them spread (underground stems) Have leaves, called fronds- which uncurl as they grow Horsetails Cane-like stems, grow in whorl pattern around stem Wet, marshy habitats Stems- hollow and contain silica Club Mosses Look similar to true mosses but have vascular tissue, roots, stems, and leaves

6. Seed Vascular Plants *seeds are plant embryos in a protective coating Gymnosperms Seeds are not in a fruit Cycads- large, woody cones Gingkos- round, grape like seeds, not in cones Conifers- cone bearing such as pine trees Angiosperms Produce flowers and fruits Flowers are reproductive system Use seeds to reproduce- but not in a fruit Use seeds to reproduce, but in a fruit

7. Your assignment!! In addition to reading and doing your text p. 110-116. (You can just read p. 117), you should do the following: 1.Think of 10 plants that you will see (once the snow melts…) 2.Make a t-chart and list them under non-vascular or vascular. 3.As a challenge, see if you can add (for vascular plants) whether they are seedless or seeded, and if seeded, gymnosperms or angiosperms. Example: Non-VascularVascular 1. Moss 2. White pine (seeded, gymnosperm) 3. Tulip (seeded, angiosperm)
