Plants transport water and assimilates through specialised tissues. Fig. 4.1 shows a tissue plan of a vertical section through part of a leaf. On Fig. 4.1, identify with a letter X the position of the xylem phloem. The answer to this question should be drawn on Fig. 4.1. (b).
Xylem and phloem are involved in transport in plants. The graph shows the effect of pressure gradient on the velocity of flow within three xylem vessels. (i) Describe the effect of pressure gradient and radius on the velocity of flow within the xylem vessels. (2)
Xylem is a specialized tissue in plants responsible for transporting water and dissolved minerals from the roots to the other parts of the plant, such as the leaves and stems. It is composed of several types of cells, including vessel elements and tracheids, which form long, interconnected tubes.
Xylem and phloem are the tissues that transport substances around a plant. Lignin for strength. Cells are empty and end walls are missing. water and minerals. (one way flow). End walls of cells have holes in them (sieve plates). Carries sugar solution (glucose) to all parts of the plant. Two way flow of sugar solution.
24 wrz 2024 · If you are asked to identify the xylem or phloem in a diagram showing a cross-section of a root, stem or leaf just remember that xylem is always on the inside and phloem is always on the outside.
