Describe diffusion about absorption and transport of mineral salts
Diffusion is a process by which mineral salts are absorbed and transported within plants. In diffusion, mineral salts move from an area of high concentration to an area of low concentration, allowing them to be taken up by plant roots and transported to various parts of the plant.
When plants absorb mineral salts, they first take them up through their roots. This process occurs through diffusion, as mineral salts move from the soil, where they are in high concentration, to the root hairs, where they are in lower concentration. The mineral salts are then transported through the plant's vascular system, which consists of xylem and phloem vessels. Xylem vessels transport water and mineral salts upward from the roots to other parts of the plant, while phloem vessels transport organic nutrients and mineral salts downward to where they are needed.
Diffusion plays a crucial role in the absorption and transport of mineral salts within plants, allowing them to obtain the nutrients they need to grow and thrive. By efficiently moving mineral salts from the soil to various parts of the plant, diffusion ensures that plants can carry out essential functions such as photosynthesis, growth, and reproduction.
