2019年3月28日 · Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves. Phloem is the other type of transport tissue; it transports sucrose and other nutrients throughout the plant.

2023年7月11日 · Phloem transports organic substances, such as sugars produced during photosynthesis, from the leaves to other parts of the plant. Transports water and minerals in support of photosynthesis and transpiration. Xylem also functions as …

In the fascinating world of botany, xylem plays a crucial role in the growth and development of plants. Understanding the various types of xylem, especially primary xylem, is essential for appreciating how plants transport water and nutrients from the roots to the leaves.Primary xylem is the first vascular tissue to develop and is vital for the transportation of water and minerals, …

2024年12月31日 · Together with phloem (tissue that conducts sugars from the leaves to the rest of the plant), xylem is found in all vascular plants, including the seedless club mosses, ferns, horsetails, as well as all angiosperms (flowering plants) and gymnosperms (plants with seeds unenclosed in an ovary).

2024年9月20日 · Xylem primarily handles the movement of water and dissolved minerals from roots to leaves. Phloem is responsible for distributing organic nutrients, particularly sugars produced via photosynthesis, throughout the plant.

2024年12月11日 · In the leaves the vascular bundles form the midrib and veins and therefore spread from the centre of the leaf in a parallel line. The xylem tissue is found on the upper side of the bundles (closest to the upper epidermis)

2024年11月23日 · Xylem is the tissue responsible for supporting the plant as well as for the storage and long-distance transport of water and nutrients, including the transfer of water-soluble growth factors from the organs of synthesis to the target organs.

2025年2月6日 · In Stems and Leaves: Within these organs, xylem is a component of the vascular bundles and is typically found at the center or the innermost part, providing structural support and facilitating water transport.

2020年8月26日 · Xylem and phloem in leaves. Photosynthesis in leaves requires a lot of water from the xylem and produces a lot of sugar for the phloem. The xylem and phloem enter a plant’s leaves via their petiole – a short stalk that connects a leaf to a branch.

2022年5月14日 · At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the finest veins and enters the cells of the spongy and palisade layers. Here some of the water may be used in metabolism, but most is lost in transpiration.
