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

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

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

Capillary action

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

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