Final answer:
Xylem and phloem are plant tissues responsible for transporting water, nutrients, and other substances throughout the plant. They also provide support to the plant.
Step-by-step explanation:
Xylem and phloem are two types of plant tissues that are responsible for the transport of water, nutrients, and other substances throughout the plant. Xylem transports water and minerals from the roots to the leaves, while phloem transports sugars, amino acids, and hormones to various parts of the plant.
The xylem and phloem are part of the vascular system, which not only transports substances but also provides support to the plant. Xylem cells have thick walls made of a strong substance called lignin, which helps in maintaining the plant's structure and preventing collapse. Phloem cells, on the other hand, have tubes that allow for the movement of sugars and other substances.
Together, xylem and phloem play crucial roles in plant growth, development, and survival by ensuring the efficient transport of water, nutrients, and other essential substances.
