1. Plants: Structure and Processes

2. Plant structures

3. Roots Absorb water, minerals Hold the plants in soil
Store food (as sugar or starch)

4. Roots
Root hair and root cap

5. Roots Root systems tap root – gymnosperms and dicots
fibrous root - monocots

6. Stems Support to plant body Leaves and photosynthesis
Contain reproductive structures
Transport material up and down
Some stems store material

7. Stems
Herbaceous and woody stems

8. Leaves
Increase surface area
Chlorophyll and photosynthesis

9. Leaves
Leave cells arranged in layers

10. Flowers
Sepals, Petals, Stamens and Pistils
Flowers and pollination

19. Reproduction
From flower to fruit

20. Reproduction
From seed to a plant

21. Reproduction
Other modes

22. Development
Seed germination and plant development

23. Development Plant hormones regulate growth
Auxin and movement towards light
Gibberellin and ethylene (use in agriculture)

24. Plant Tropism Growth in response to external factors (stimuli)
Positive or negative

25. Plant Tropism
Light (phototropism)
Shoots positive, roots negative

26. Plant Tropism
Gravity (gravitropism)
Shoots negative, roots positive

27. Plant Tropism
Seasonal responses

28. Plant Tropism Length of day (short and long day plants)
Seasons and leaf loss
Deciduous vs. evergreen
