Plants -Multicellular Eukaryotes that photosynthesize. -Cell walls made of cellulose

Types of plants—Non vascular 1. Bryophytes—Mosses, liverworts, hornworts. --Reproduction only in water --No vascular tissue --draw water only by osmosis Vascular tissue

2. Seedless Vascular plants —ferns and their relatives --Reproduce using spores --Have vascular tissue to transport food and water --Xylem-moves water through the plant --Phloem-moves food through the plant spores Xylem and phloem

Microscope break… At this point, you will use the microscopes to look at a cross section of a fern leaf, which includes the sorus, which is the spore producing part of a fern leaf. You will then look at a fern gametophyte (prothallium). Sketch each on low power and we will label when done.

Vascular plants 3. Gymnosperms– conifers, cykads, ginkgoes, gnetophytes --reproduce by seeds—have no protective coat (naked seed).. --includes pine, spruce, fir trees --sperm from pollen fertilizes egg

Gymnosperms continued ! Pinecones (female) contain the seeds Male cones contain the pollen---- Where are the different types of cones located on the tree?

4. Angiosperms—Flowering plants --Have flowers which attract insects and birds for more efficient pollination. --have ovary—covers seed (fruit) --animals may carry fruit to new locations—other dispersal mechanisms?

Diversity of Angiosperms Two classes: Comparison of monocots and dicots. Monocots—corn, lilly, grass, orchids, palms, etc. Dicots—roses, clover, tomatoes, daisies, etc. Dicotyledonae (dicots) Monocotyledonae (monocots) (Pg. 570)
