  2. Xylem - Wikipedia

    en.wikipedia.org/wiki/Xylem

    The transport is passive, not powered by energy spent by the tracheary elements themselves, which are dead by maturity and no longer have living contents. Transporting sap upwards becomes more difficult as the height of a plant increases and upwards transport of water by xylem is considered to limit the maximum height of trees. [11]

  3. Polar auxin transport - Wikipedia

    en.wikipedia.org/wiki/Polar_auxin_transport

    Polar auxin transport (PAT) is directional and active flow of auxin molecules through the plant tissues. The flow of auxin molecules through the neighboring cells is driven by carriers (type of membrane transport protein) in the cell-to-cell fashion (from one cell to other cell and then to the next one) and the direction of the flow is determined by the localization of the carriers on the ...

    The Maharashtra State Board of Secondary and Higher Secondary Education (Abbreviation: MSBSHSE) is a statutory and autonomous body established under the "Maharashtra Secondary Boards Act" 1965 (amended in 1977). [1] Most important task of the board, among few others, is to conduct the SSC for 10th class and HSC for 12th class examinations. [2]

    Dr. Dinesh Prasad Saklani is the director of NCERT since 2022. [2] In 2023, NCERT constituted a 19-member committee, including author and Infosys Foundation chair Sudha Murthy, singer Shankar Mahadevan, and Manjul Bhargava to finalize the curriculum, textbooks and learning material for classes 3 to 12.

  6. Apoplast - Wikipedia

    en.wikipedia.org/wiki/Apoplast

    Transport velocity is higher (transport is faster) in the apoplast than in the symplast. [9] This method of transport also accounts for a higher proportion of water transport in plant tissues than does symplastic transport. [10] The apoplastic pathway is also involved in passive exclusion.

  7. Plant stem - Wikipedia

    en.wikipedia.org/wiki/Plant_stem

    In most plants, stems are located above the soil surface, but some plants have underground stems. Stems have several main functions: [3] Support for and the elevation of leaves, flowers, and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.

  8. Active transport - Wikipedia

    en.wikipedia.org/wiki/Active_transport

    Active transport often takes place in the internal lining of the small intestine. Plants need to absorb mineral salts from the soil or other sources, but these salts exist in very dilute solution. Active transport enables these cells to take up salts from this dilute solution against the direction of the concentration gradient.

  9. Soil-plant-atmosphere continuum - Wikipedia

    en.wikipedia.org/wiki/Soil-plant-atmosphere...

    The transport of water along this pathway occurs in components, variously defined among scientific disciplines: Soil physics characterizes water in soil in terms of tension, Physiology of plants and animals characterizes water in organisms in terms of diffusion pressure deficit, and
