Question

Photosynthate is translocated through?
a. Sieve Tubes/Phloem Cells
b. Tracheids
c. Xylem Vessels
d. Latex Ducts

Answer 1

Hint: Photosynthate is translocated by the breathing tissue in vascular plants that translocates the soluble organic compounds produced during photosynthesis, especially the sugar sucrose, to parts of the plant where it is required. This transport process is known as translocation. In trees, this part is the deepest layer of trees.

Complete answer:
Photosynthate is the final product of photosynthesis and is primarily sugar that is translocated by the sieve tubes of phloem cells in bi-direction to reach to several parts of the plants either for storage or utilization in several activities included in the plant body or system.

Tracheids are the hydro-conducting and mechanical supporting cells of gymnosperms; water is transported vertically through endplates and alongside through pits.

Xylem is the specific tissue of vascular plants that carries water and nutrients from the plant-soil line to stems and leaves and gives powered support and storage.

Latex Ducts composed of thick-walled, greatly elongated, and much-branched ducts containing a creamy or yellowish colored juice known as latex. They contain plentiful nuclei that lie entrenched in the thin lining layer of protoplasm.

Hence, the correct answer is option (A).

Note: Sieve elements are the sort of cells that are accountable for transporting sugars through the plant. At maturity, they are devoid of the nucleus and have very scarce organelles, so they count on companion cells or albuminous cells for most of their metabolic requirements. Sieve tube cells do comprise vacuoles and other organelles, such as ribosomes before they develop, but these mostly migrate to the cell wall and liquefy at maturity; this ensures there is little to hamper the movement of fluids.
