Evolution of Plants

Nonvascular plants Examples: green algae and mosses Does NOT have a transport system Found in water or damp places Tend to be small

Vascular Plants Have vascular tissue – specialized tissue to transport water and nutrients Xylem – moves water up from the roots Phloem – carries nutrients made by photosynthesis

Seed Plants 1. Cones Male cones make pollen Pollen carried by wind to female cones Female cones have seeds on it Pollination – transfer of pollen from male to female reproductive structures

2. Flowers Can have male and female parts in the same flower Petals attract pollinators (ex: bees, hummingbirds) Pollen carried by animals or wind Ovaries develop into a fruit to protect seeds

Plant Tissues Roots – anchor the plant and absorbs water and nutrients Stems – transport system (xylem and phloem) and protection Leaves – photosynthesis and lets carbon dioxide in/out (stomata)
