1. Botany-the study of plants
more than 350,000 species

2. Uses of plants:
-agriculture/food
-medicines
-clothing and fabric dyes
-fuels

3. Plant Ecology
-recycle water, oxygen, carbon dioxide, and inorganic molecules, and maintain soil

6. pollinators-type of relationship?
fungi on plant roots-fungus increases root's ability to absorb water and root supplies fungus with energy-what type of relationship?

7. Plant Evolution and Classification
How plants adapted to land:
-cuticle-waxy, protective covering that prevents water loss in plants
-developed spores which are haploid? reproductive cells allowing dispersal
-developed seeds-embryo surrounded by protective coat and has endosperm, which provides nourishment for plant

8. Transporting materials in plants
-vascular tissue-tissue that transports water and dissolved substances in plants, provides support
-xylem-carries water from roots to stems and leaves
-phloem-carries organic compounds, carbohydrates
-woody tissue-formed from several layers of xylem
