1. Plants!

2. Characteristics Multicellular Eukaryotes
Autotrophic: produce their own food through photosynthesis

3. Photosynthesis Requires: Light, Carbon Dioxide, Water
Produces: Oxygen, Glucose (a sugar)
Pigment used for photosynthesis: green pigment called chlorophyll
Organelle where photosynthesis takes place: chloroplast

4. Two Types
Vascular plants: contain tissues made up of tubelike, elongated cells through which water, food, & other materials are transported (ex. Trees, flowers, ferns)
Nonvascular plants: do not have tissues; nutrients move through osmosis and diffusion (ex. mosses)
Xylem- transports water
Phloem – transports food ( sugar and nutrients)

5. Seed Plants Gymnosperms: seed is enclosed in a pine cone/ “naked seed”
Angiosperms: seeds are enclosed in a fruit

6. Special Features
Roots: used to obtain nutrients/ water from the soil; anchor plant; acculumlate starch reserves
Rhizoids– baby roots
Stem: structural support for growth & transports food, water, & materials; may serve as food storage
Vascular bundles: x and p
Leaves: photosynthesis! (in the mesophyll) by traps light energy & grows toward sunlight
Cuticle: a waxy waterproof coating / prevents water loss

7. Special Features Leaves continued…..
Stomata: pores on the bottom of the leaf that allow gases to enter and leave
Guard cells: open and close to regulate decrease water loss in times of drought

8. Special Features
Flower: used for sexual reproduction– smell and color attracts animals
Fruit: a sugar-filled coating filled with seeds; used to attract animals to disperse seeds
Spores: (primitive seeds) single haploid cell with hard outer wall/ asexual reproduction
Seeds: an embryo & food supply covered by a protective coat and assist in dispersal, *
