Plants & Classification Notes There will be a quiz on this material soon.  Please take notes 

What are plants? Multi-cellular organisms Make own food (photosynthesis) Have chloroplasts Have rigid cell walls made of cellulose Found all over the world

Plants provide: Food Oxygen Medicines Building materials Textiles (fibers) Coloring pigments

Plant Parts Roots Anchors the plant Absorbs water & minerals Storage AKA “tuber” Pic is hyperlink

Plant Parts Stems Support plant Storage Food & water “highway” Xylem carries water & minerals; goes up stem only Phloem carries food; goes up & down the stem Pic is hyperlink

Plant Parts Leaves Provide food (photosynthesis) Have chloroplasts (green coloring-chlorophyll) Transpiration (“sweating”) Respiration Pic is hyperlink

Plant Classification

Plants Without Seeds Need water to reproduce Reproduce with spores Include Mosses Ferns Horsetails Bladderworts Upper right pic is hyperlink

Plants with Seeds 2 types Found all over the world Upper right pic is hyperlink

Gymnosperms Means “naked seed” Often have cones & needle-like leaves Do not have flowers Ex: conifers, gingko

Angiosperms Flowering plants Largest group Pic is hyperlink

Angiosperms Monocots Has 1 food part Parallel veins Petals in groups of 3, 6, 9 Xylem & phloem scattered throughout stem

Monocots

Angiosperms Dicots Have 2 food parts Net-like veins Petals in groups of 4 or 5 Xylem & phloem are ring-like in stem

Dicots

Homework Scavenger Hunt!!! Find the following things: A root A stem A leaf 3 examples of seeds Paste them on a sheet of paper and label each of them Be sure to include your name!!!
