2. Classification of Angiosperms

3. Cotyledon: A plant’s first leaf/leaves developing out of the seed. Cotyledon

4. Angiosperms 2 classes: Monocotyledons: ONE seed leaf Dicotyledons:TWO seed leaves

5. Monocots and dicots differ in their arrangement of their vascular tissue. Elongated cells in plants, which function to transport WATER, and FOOD. What is Vascular Tissue? Vascular Bundles

6. What are the types of Vascular Tissue? Xylem: type of vascular tissue which transports water. Xylem Cell characteristics: Dead and larger diameter. Xylem

7. Phloem: type of vascular tissue which transports sugars. Phloem Cell characteristics : Alive and average diameter Phloem

8. Which direction does water/sugar travel in a plant? Water: from the roots to the rest of the plant. Sugar: from the leaves to the rest of the plant.

9. Monocot Roots 10x 100x Phloem Cells Vascular Bundles Arranged in ring Xylem

10. Dicot Root 40x 40X Xylem in an “X” Phloem between arms of “X”

11. Ready for Roots? A. B. C. D.

12. Monocot Stems 10x 40x Phloem Cells Xylem 10X 40X Scattered Vascular Bundles, which look like faces

13. Dicot Stems 10x 40x Phloem Cells Xylem 40X 10X Vascular Bundles arranged in a ring

14. How’s Your Stem Strength? A. B. Sunflower C.

15. Leaves Vein of Leaf One Mesophyll Layer MONOCOT DICOT Palisade Mesophyll Layer Spongy Mesophyll Layer 40X

16. Good Looking Leaves A. B. C.

17. Summary of Moncots vs. Dicots Number of cotyledons: 12 Root Arrangement:VBs in a ringXylem forms an “X” Stem Arrangement:Scattered VBs VBs in a ring Leaf Arrangement: One Mesophyll Layer Two Mesophyll Layers
