What substance travel from the roots to leaves of plant ?
Answers
Answer:
The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots
Answer:
Water and nutrients taken up by the roots are carried to the leaves by stems. The food that the leaves produce then goes to other sections of the plant. The cells that perform this function are known as xylem cells. They are responsible for moving water.
Explanation:
Minerals and water are transferred from the soil to the leaves by xylem cells in plants. Mineral salts in the soil are absorbed by plants through their roots, and then translocated upwards with water through the xylem. The stem, roots, and leaves all have interconnected xylem cells that form a conducting channel that reaches all plant parts. Ions are obtained by root cells from the soil, resulting in a differential in ion concentration between the roots and the soil. As a result, water flows continuously into the xylem.
Transportation to and from the source
The roots distribute water to all areas of the plant. The following is the procedure for transportation:
The plants continuously absorb water through their roots. All components of the plant, including the leaves, receive this water via the stem.
Only a small amount of water is retained or used by the plant in photosynthesis. The rest evaporates as water vapour into the sky via the Stomata found in the epidermis of the leaves and other aerial portions of the plant.
This causes suction pressure, which pulls water up from the roots' xylem to the stem, and finally to the leaves.
The stronger the strain, the narrower the diameter of xylem tissues in the form of capillary tubes (tracheids and fibres).
When the xylem vessels are empty, such as when water is lost through transpiration, water from below rises through a capillary force into them.
