Pholem functions to transport which of the following?

Pholem functions to transport which of the following?

• A. Water from roots to leaves
• B. Food and compounds from leaves to other parts
• C. Water and minerals from soil
• D. Structural support for stems

Answer: (B)

Phloem moves the products of photosynthesis, mainly sugars, from the parts of the plant that generate them (typically the leaves) to other regions that need them (such as growing shoots, roots, or fruits). This source-to-sink transport supports growth, storage, and development by delivering energy-rich compounds where they’re required. The flow uses a pressure-driven mechanism: sugars are actively loaded into phloem cells in the leaves, drawing in water and creating high pressure that pushes sap through sieve tubes toward sinks where sugars are unloaded and used or stored. Water and minerals, meanwhile, are carried upward from the roots to the shoots by the xylem, not the phloem. Phloem also isn’t responsible for structural support, which comes from supportive tissues like sclerenchyma.
