  2. Xylem - Wikipedia

    en.wikipedia.org/wiki/Xylem

    Xylem is one of the two types of transport tissue in vascular plants, the other being phloem; both of these are part of the vascular bundle. The basic function of the xylem is to transport water upward from the roots to parts of the plants such as stems and leaves, but it also transports nutrients.

Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem ...

  4. Vessel element - Wikipedia

    en.wikipedia.org/wiki/Vessel_element

    The presence of vessels in xylem has been considered to be one of the key innovations that led to the success of the flowering plants. It was once thought that vessel elements were an evolutionary innovation of flowering plants, but their absence from some basal angiosperms and their presence in some members of the Gnetales suggest that this hypothesis must be re-examined; vessel elements in ...

  5. Ascent of sap - Wikipedia

    en.wikipedia.org/wiki/Ascent_of_sap

    Godlewski (1884) proposed the relay-pump theory to explain the ascent of sap. He believed water potential of living cells of the xylem, such as xylem parenchyma, changed rhythmically causing water to rise. However, this was soon discredited as even when the living cells are killed by heat or chemical treatment water continued to rise in the ...

  7. Transpiration stream - Wikipedia

    en.wikipedia.org/wiki/Transpiration_stream

    3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata. In plants, the transpiration stream is the uninterrupted stream of water and solutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/ apoplast ...

  9. Vascular bundle - Wikipedia

    en.wikipedia.org/wiki/Vascular_bundle

    The transport itself happens in the stem, which exists in two forms: xylem and phloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues. There is also a tissue between xylem and phloem, which is the cambium.
