    Study Notes

    Plant Essentials

    • Transpiration is the loss of water from plants.
    • Transpiration influences water uptake.
    • Properties of water, like cohesion and adhesion, are vital for water transport.
    • Other properties of water may also be involved in water loss/flow.
    • Water is lost through stomata.
    • Water flow is resisted in some parts of the plant.
    • Possible sources of water loss include soil, leaves, other plant tissues, and the air.
    • Transpiration is a key part of how plants take up water.
    • Water resistance is discussed in terms of the plant's structures affecting it.
