1 Plant Diversity

2 What is a Plant? Multicellular eukaryotes Cell walls: cellulose
Multicellular embryos Photosynthesis Green pigments

3 To Survive Sunlight Water and Minerals Gas Exchange
CO2  O2 Movement of Water and Nutrients

4 Bryophytes Life cycle depends on water Lack vascular tissue
Draw up water through osmosis Mosses, Liverworts, & Hornworts Gametophyte is the dominant stage

5 Seedless Vascular Plants
Vascular Tissue move fluids throughout the plant xylem & phloem Club Mosses, Horsetails, & Ferns Ferns: diploid sporphyte is the dominant stage

6 Gynosperms: Seed Plants
Reproduce in areas without water Flowers or Cones Pollination: transfer of sperm Seeds: protect the embryo Gnetophytes, Cycads, Ginkgoes, & Conifers

7 Angiosperms – Flowering Plants
Flowers: unique reproductive organs Ovaries – surround & protect the seed Cotyledons - # seed leaves Monocot – 1 seed leaf Dicot – 2 seed leaves Life Spans: annual, biennial, perennial
