1. Plant Structure & Function

2. Main Plant Tissues • Dermal Tissue - covers the outside of the plant & protects it • Ground Tissue - inside the dermal tissue; provides support, stores materials & is the site of photosynthesis • Vascular Tissue - transports water & nutrients throughout the plant • Xylem transports water • Phloem transports food

3. Roots • Roots anchor plants & absorb mineral nutrients from the soil

4. root cap Root Parts • 1. Root cap covers the tip & • protects the growing part of the root

5. Apical meristem . • 2. Apical meristem is where growth occurs.

6. Vascular Cylinder 3. Vascular cylinder is in the center of the root & contains xylem and phloem

7. . 4. Root hairs increase surface area to absorb water & nutrients.

9. Stems • Stems support plants, transport materials & provide storage

10. Primary Growth • Occurs in apical meristem • Lengthens roots & stems

11. Secondary Growth • Occurs in lateral meristems • Adds to the width of roots and stems

12. Leaves • Leaves collect sunlight for photosynthesis • The top of a leaf contains most of the chloroplasts & is where most photosynthesis takes place

13. Leaves • Gases are exchanged through openings called stomata, which are opened & closed by surrounding cells called guard cells

15. sepal Flowers Flowers contain sepals and petals, which are often brightly colored to attract animal pollinators

16. stamen filament anther • A stamen is the male structure of the flower. • anther produces pollen grains • filament supports the anther

17. stigma style pistil ovary • The innermost layer of a flower is the female pistil. • stigma is sticky tip • style is tube leading from stigma to ovary • ovary produces egg cells
