Plant Transport System

  1. 1. Circulatory System in Plants
  2. 2. Circulatory System Plants, like animals, also have a circulatory system.
  3. 3. Circulatory System <ul><li>2 separate sets of tubes that run through the leaves, stems and roots. </li></ul><ul><li>xylem , phloem . </li></ul>
  4. 4. Circulatory System <ul><li>xylem tubes turned red when placed in water containing food dye. </li></ul>
  5. 5. Circulatory System The phloem tubes carry food made in the leaves to the other parts of the plants.
  6. 6. Circulatory System <ul><li>food made in the leaves transported to all parts of the plant by phloem </li></ul><ul><li>water and dissolved mineral salts absorbed by the roots must be carried to all parts of the plant by xylem </li></ul>
  7. 10. <ul><li>To anchor plant in the soil </li></ul><ul><li>To absorb minerals and water from the soil </li></ul><ul><li>To store food </li></ul><ul><li>Roots form a passage way for water and dissolved substances from the root into the stem and also for foods from the stem down into the root. </li></ul>Function of root
  8. 11. Function of root hair <ul><li>To increase the area of absorption </li></ul>
  9. 12. <ul><li>layer of active dividing cells between the xylem and phloem </li></ul><ul><li>To absorb minerals and water from the soil </li></ul><ul><li>divide to form secondary xylem and phloem </li></ul><ul><li>Roots form a passage way for water and dissolved substances from the root into the stem and also for foods from the stem down into the root. </li></ul>Cambium
