3. 1.1 Parts of a Plant I.Vegetative A.leaves B.stem C.roots II.Reproductive A. flower B. fruit C. seed

4. 1.2 Leaves I.Function A.Primary producers B.Produce food through photosynthesis C.Carbon dioxide plus water plus light energy produce a simple sugar and oxygen D.Carbohydrates move down stem from leaf to root E.Used by other parts of the plant and by animals - respiration

5. II.External structure (Parts of a leaf) A.Petiole – leaf stem (stalk) sessile = no petiole B.Blade 1.Overall Shape – (lanceolate cordate) 2.Margin – outside edge (entire undulate serrate) 3.Midrib – large center vein 4.Veins – extend from midrib 5.Arrangement on stem – (opposite alternate whorled)

6. III.Internal leaf structure A.Epidermis – upper and lower outside layer B.Palisade/ mesophyll – contain chloroplasts C.Stoma – holes in epidermis D.Guard cells – control opening and closing of stomata E.Transpiration – release of water through leaf

8. 1.3 – Stems (dicots) I.External structure A.Terminal bud – A.Topmost bud B.Contains apical meristem C.Hormones inhibit side buds B.Axillary bud – side buds C.Lenticel – breathing pore D.Scars – bud scale and leaf E.Node – space between buds

9. II.Internal Structure A.Conducts water up and food down B.Xylem – hollow water conducting tubes C.Phloem – food transport from leaves to roots D.Cambium 1.Separates xylem and phloem 2.Produces new cells meristem E.Bark 1.epidermis 2.outside protective layer

10. IV.Monocots 1.Plant types A.grasses B.palms C.flowering (ex: Lilies) 2.Stem anatomy A.vascular bundles B.xylem and phloem together C.no circling cambium 3.Root system A.fibrous B.many small roots

11. Cloze notes FROM TEXT pages 31-33 from this point

12. 1. 4 Roots Function – anchor plant – absorb water and nutrients from soil – store plant food Structure – root cap – root hairs

13. embryonic

14. Root Systems – tap – single root with side roots (trees) hard to transplant deep growing – fibrous – many small roots (annual flowers grasses) shallow growing same depth

16. 1.5 Reproductive Plant Parts (page 33) I.Flowers A.Function 1.To attract insects or birds 2.To catch and/or release wind born pollen 3.Pollination – moving pollen from flower to flower 4.Purpose is to produce seeds  new plants

18. B.Parts of a flower 1.Complete – contains male and female parts in same flower 2.Incomplete – male and female parts in separate flowers 3.Sepals – leaf like parts that protect the flower bud 4.Petals – modified leaves, colorful

19. 5.Stamen – male reproductive parts a.Filament – short stalk b.Anther- pollen producing

20. 6.Pistil – female reproductive parts a.Stigma – receives pollen b.Style – stem that transfers pollen to ovary c.Ovary – holds egg cells d.Fertilization occurs here e.Fertilized eggs (ovules) become seeds f.Carpel – space where ovules form
