Plant Structure And Transport

1. Plant Structure And Transport

3. Chapter 13: Plant Structure And Transport • Main Parts Of Plant: • 1. Roots • 2. Stem • 3. Leaves • 4. Flowers • 5. Seed • Below Ground = Roots • Above Ground = Shoot

4. Chapter 13: Plant Structure And Transport • The Functions of the Main Parts: • 1. The Root: • Anchor the plant • Take in water (osmosis) and minerals (active transport) • Store Food

5. Chapter 13: Plant Structure And Transport • 2. The Stem: • To hold up the parts of the plant • Main function is to transport substances: • To carry water and minerals • To carry food

6. Chapter 13: Plant Structure And Transport • Vascular Tissue (Transport): • 1. Xylem: • Carries water and nutrientsUP the plant FROM THE ROOTS to the leaves (capillary action) • 2. Phloem: • Carries food FROM THE LEAVES to all parts of the plant

7. Capillary action

9. Chapter 13: Plant Structure And Transport • 3. The Leaves: • Photosynthesis • Exchange of Oxygen and Carbon Dioxide (stomata) • Loss of water vapour (evaporate/transpiration)

11. Chlorophyll

12. Chapter 13: Plant Structure And Transport • Transpiration: • Transpiration is the loss of water vapour from the surface of a plant • Trees get water from the roots to the leaves via this process

13. Chapter 13: Plant Structure And Transport • 4. The Flower: • Reproduction • Production of seeds

14. Pollen grains

16. Chapter 13: Plant Structure And Transport • 5. The Seed : small embryonic plant enclosed in a covering called the seed coat, usually with some stored food
