n.木质部(植物中将水分和矿物质从根部向上输送的组织)

Xylem is the tissue in plants responsible for the upward transport of water and minerals from the roots to the leaves.
木质部是植物中负责将水和矿物质从根部向上输送到叶子的组织。
The xylem vessels in a tree trunk are essential for its structural support as well as water transportation.
树干中的导管木质部对于其结构支撑以及水分运输至关重要。
In botany, the differentiation of primary xylem occurs during the early stages of a plant's growth.
在植物学中，初级木质部的分化发生在植物生长的早期阶段。
When a tree is cut down, you can see the concentric rings that represent annual growth, with each ring composed of both phloem and xylem.
当砍倒一棵树时，你可以看到代表年轮的同心圆，每一圈都由韧皮部和木质部组成。
Drought stress can lead to the formation of cavities in xylem tissues, impairing the water conductivity.
干旱压力可能导致木质部组织内形成空腔，从而影响水分传导能力。
Some fungi can form symbiotic relationships with plant roots, colonizing the surrounding xylem and enhancing nutrient uptake.
有些真菌能够与植物根系形成共生关系，殖民周围的木质部并提高营养吸收效率。
Transpiration pulls water through the xylem against gravity, ensuring continuous flow from the roots to the leaves.
蒸腾作用克服重力拉动水分通过木质部，确保了从根到叶的连续流动。
In some coniferous trees, tracheids are the main elements of xylem responsible for water transport.
在某些针叶树中，导管分子是木质部的主要组成部分，负责水分输送。
Pathogens such as bacteria or fungi can infect xylem cells, leading to diseases like gummosis or bacterial wilt.
细菌或真菌等病原体可以感染木质部细胞，导致如流胶病或细菌性萎蔫病等病症。
Research on xylem structure and function has implications for improving plant drought resistance and developing sustainable forestry practices.
对木质部结构和功能的研究对增强植物抗旱性和制定可持续林业实践具有重要意义。
