WebbPhloem cell– this cell helps the transportation of food up and down the plants. They have the cell walls replaced into sieve plates that allow the food to dissolve through them. The companion cell, adjacent to the phloem cells, has a lot of mitochondria that release energy to move the dissolved food up and down through the plant. Webbcells support the phloem cells and aid in the movement of substances in and out of the phloem. Ground tissue produces and stores sugars, and helps support the plant. • Parenchyma cells have a thin cell wall and a large central vacuole. • Collenchyma cells have strong, flexible cell walls that help support plant organs.

Primary phloem originates from the procambial regions in meristems, while secondary phloem originates from the vascular cambium. Phloem contains specialized cell types.

WebbThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant. WebbIt asks how cells are organised to form a tissue, using xylem and phloem as examples.
