Answer:
organic molecules
Step-by-step explanation:
Translocation refers to mobility, that is, the transport of organic substances produced in photosynthesis, from the leaves to other plant organs, by the phloem.
On the sheet, organic substances can have two export routes to other organs:
- Apoplast pathway - corresponds to approximately 5% of the leaf volume, depending on the plant species;
- Simplast route - from cell to cell, through the cytoplasm.
The transport out of the leaf occurs when the solutes, after crossing the mesophile, enter the apoplast and are transferred to the phloem and, afterwards, out of the leaf. Some are transported quickly, such as nitrogen and phosphorus, while others such as calcium and boron, may be partially mobile or immobile.
