The function of xylem in plant's -1m
Answers
Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves.
Xylem plays an essential ‘supporting’ role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.
The water-transporting cells of mature xylem are dead, and therefore the transport of water is mostly a passive process with a very small active root pressure component.
In most woody plants, xylem grows by the division and differentiation of cells of a bifacial lateral meristem, the vascular cambium, which produces secondary xylem and phloem.
Xylem is wood, one of the world's most abundant and valuable renewable raw materials.
The morphology, frequency and distribution of xylem cell types determine its biological, physical and chemical properties, and the resulting properties of wood.
The chemical and physical properties of wood determine its role in the carbon cycle through its carbon storing capacity and its resistance to decay when alive or dead, and in various sediments.
The chemical and physical properties of wood are themselves determined by the composition and interactions of the three polymers, cellulose, hemicellulose and lignin.
The difference between a woody and herbaceous plant depends on the expression of a small number of regulatory genes controlling the duration and quantity of xylem formation.
Genetic engineering has great potential to develop xylem with desired qualities for specific purposes.
Answer:
Xylem helps in transportation of water and minerals to different parts of the plant body. Xylem and Phloem are together known as complex tissue
