Answer:

B) sugars; leaf; apical meristem is the correct answer.

Explanation:

  • Phloem transports sugars from the leaf source to the apical meristem sink.
  • Phloem is a living system that carries and transports the food prepared in the leaves to all parts of the plant.
  • Phloem cells are found outside xylem.

Phloem is comprised of

  • companion cells
  • sieve cells.
  • phloem fibers
  • phloem parenchyma cells

Phloem transfers food everywhere the plant by this way:

  • It performs this by a series of tubes that join source tissues to the sinks tissues.
  • The food prepared in the leaves is loaded in the sieve tubes of the phloem and the high pressure produced in the phloem transfer the food to all parts of the plant. Thus mechanism through which sugars are carried is called pressure flow.

Phloem transports SUGARS from the LEAF source to the APICAL MERISTEM sink (Option B).

  • Higher vascular plants have two different transport tissues known as xylem and phloem.

  • The xylem is a specialized plant tissue that transports water (H2O) and nutrients (eg., minerals) from the roots to stems and leaves.

  • Moreover, the phloem is another specialized plant tissue that transports soluble organic compounds synthesized during photosynthesis (eg., sugars) in the leaves to all other parts of the plant.

In conclusion, phloem transports SUGARS from the LEAF source to the APICAL MERISTEM sink (Option B).
