• • Xylem Phloem Cuticle Stomata Guard Cells Photosynthesis Cellular Respiration Chloroplast

Basic Plant Parts • Roots – absorb water, minerals, and nutrients • Stems – transport water, minerals, and nutrients • Leaves – capture sunlight and produce sugar photosynthesis.

Stems • Consist of a vascular network of cells for transport. • Xylem – transports water and minerals • Phloem – transports food (sugar)

Leaves • Waxy cuticle on surface • Palisade Mesophyll – layer of cells beneath the epidermis that contain chlorophyll • Vein – contains xylem and phloem • Stomata – opening on bottom of leaf that allow gas exchange and water loss • Guard cells – regulate opening of stomata

• How can a plant modify its leaves: -to capture more sunlight? -to receive less sunlight? -to prevent water loss? -for protection?

TAKS question #1 • The diagram illustrates the parts of this flower. Which of these parts are not directly involved in sexual • reproduction? • A Stigma and style • B Sepal and pedicel • C Anther and filament • D Receptacle and ovary

TAKS question #2 • Which structure regulates gas exchange during the processes of photosynthesis • and respiration? • AQ • BR • CS • DT

• Animal Dispersal • Wind Dispersal • Floating in water

Some animals bury seeds and they grow into new plants. Barbs get tangled in animal fur and carried to new places. Animals eat fruit, and after digestion the seeds are dropped in new places.

More barbs and hooks…
