1. Structure of plants Vascular plants- have roots, stems and leaves ( ) Leaves are adapted for photosynthesis- broad leaves have - Broad leafed Thin leafed

2. Structure of a leaf Epidermis- Cuticle- top of epidermis, Stomata- openings found – Allow for gas exchange C02 in (photosynthesis- O2 out (photosynthesis- H2O vapor out (transpiration- )

3. Guard cells- regulate opening & closing of stomate- Palisade Layer- below epidermis- Spongy Layer- below palisade, gas exchange, - http://www.youtube.com/watch?v=IlmgFY mbAUghttp://www.youtube.com/watch?v=IlmgFY mbAUg

4. Vascular Tissue Veins- Xylem- carries - Phloem- carries – Roots- absorb water and nutrients Root hairs-

8. Chemical Regulation Auxin- Plant hormone, causes - Phototropism- plant bends toward light, auxin – Geotropism- roots grow down, Apical Meristem- region of growth (lengthwise)-
