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

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

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

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

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