1. Today’s Agenda… Get your clickers!  Bellringer questions
Take up homework
Create a T-chart to compare seedless vascular and nonvascular plants (SP #3)
Notes on Parts of Seed Plants (SP #4)
Homework: Worksheet

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

3. Parts of a Seed Plant
Study Pack #4

4. Today’s Goals… I can identify the characteristics of seed plants.
I can explain the structure and function of roots, stems, and leaves.

5. Characteristics of Seed Plants
Most of the plants you are familiar with are seed plants
Most seed plants have leaves, stems, roots, produce seeds, and contain vascular tissue

6. Leaves Organs where photosynthesis takes place
Come in many shapes, sizes, colors
Figure 14

7. Leaf Cell Layers Upper and lower surface cells make up the epidermis
Covers and protects the leaf
A waxy cuticle covers the epidermis

8. Leaf Cell Layers Small openings in the epidermis are called stomata
Allow carbon dioxide, water, and oxygen to enter and leave the cell
Surrounded by guard cells that open and close

9. Leaf Cell Layers Below the upper epidermis is the palisade
Closely packed, long, narrow cells with many chloroplasts
Food is made here (photosynethesis takes place here)

10. Leaf Cell Layers Below the palisade is a spongy layer
Loosely arranged cells separated by air spaces
Vascular tissue is found in this layer

11. Stems Usually above ground
Support the braches, leaves, and reproductive structures
Materials move between leaves and roots through the vascular tissue

12. Roots Allow water and other substances to enter the plant
Act as anchors
Support other plant parts that are aboveground
Store food

13. What did you learn? Discussion Question
How are the structure and function of living things related?
