Notes on Vascular Tissue/ Angiosperms & Gymnosperms

2. Review Which plants are seedless plants? Which plants are seed plants?
What is the difference between vascular and nonvascular plants?

3. Review Which layer of the leaf contains the cuticle?
Which layer of the leaf has the most chloroplasts in its cells?
Which layer of the leaf contains vascular tissue?
What are stomata?
How do stomata open and close?

4. Review
What is the purpose of stems?
What purposes do roots serve?

5. PLANTS Seedless Plants Seed Plants Non vascular Vascular
Seeds in Cones
Seeds in Flowers

6. Vascular Tissue/ Angiosperms & Gymnosperms
Study Pack #6

7. Today’s Goals… I can describe the different types of vascular tissue.
I can distinguish between angiosperms and gymnosperms.

8. Vascular Tissue
Vascular system -Tube-like structures that carry water, nutrients, and other substances through the plant
Three tissues make the vascular system in a seed plant
Xylem
Phloem
Cambium

9. Vascular Tissue Xylem tissue
Made up of hollow, tubular cells that are stacked one on top of the other to form a vessel
Transport water and dissolved substances through the plant
Thick walls of xylem provide support
Runs from roots to leaves

10. Vascular Tissue Phloem tissue
Made of cells that are stacked to form tubes
Move food from where it is made to other parts of the plant where it is used or stored
Runs from leaves to roots

11. Vascular Tissue Cambium Between xylem and phloem
Produces xylem and phloem cells
These new cells make the stems and roots thicker

12. Gymnosperms Vascular plants that produce seeds not protected by fruit
Do not have flowers
Leaves are needlike or scalelike
Evergreens
Examples – pines, firs, spruces, redwoods

13. Angiosperms Has flowers and produces fruits with one or more seeds
Example: peaches

14. Importance of Seed Plants
Paper
Furniture
Clothing
Food

15. Homework…
Create a T-chart to compare angiosperms and gymnosperms
