Phloem section
Webb26 aug. 2024 · The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’. Sieve-tube members Webb6 juni 2024 · The ‘sapwood’ is the section of xylem still actively transporting water, and the ‘heartwood’ is the section which no longer does. For example in Picea Abies (what we use in the UK for a Christmas tree), once a tree reaches a certain age, “the width of the sapwood band remains more or less constant (on average 7.8 cm for dominant and 2.0 …
