Give difference between xylem and phloem......... NO COPY
Answers
Explanation:
Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.
What is the difference between xylem and phloem?
The xylem of a plant is the system of tubes and transport cells that circulates water and dissolved minerals. Plants' roots help them absorb water. If a plant's leaves need water and they are high above the ground, the xylem gets them hydrated. Xylem is made of vessels that are connected end to end for the maximum speed to move water around.
Most plants have green leaves, where the photosynthesis occurs. When those sugars are made, they need to be given to every cell in the plant for energy. The phloem cells are laid out end-to-end throughout the entire plant, transporting the sugars and other molecules created by the plant.
Also, phloem is always alive. Xylem tissue dies after one year and then develops anew (when a tree is cut down, the rings in the tree trunk are old xylem tissue. That is why each ring represents a year of the tree's life.).
