What is the path of the translocation of the food in the plant?

Solution
Translocation:
It is the transfer of nutrients and other substances from the leaves of the entire plant to other tissues.
Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but non-photosynthetic parts of plants also require carbohydrates and other organic and inorganic materials.
This shifts nutrients from sources (areas with excess carbohydrates, primarily mature leaves) to sinks (areas with a need for carbohydrates).
Some important sinks are developing leaves, roots, stems, fruits, and flowers.
Translocation occurs within a series of cells known as the phloem transport system, which is the most important digestive tissue of plants.
Nutrients move to phloem as solutes in a solution called phloem liquid.
The main nutrients that move are sugar, amino acids, and minerals, which are the most concentrated solutes in phloem liquor.
Translocations occur both upwards and downwards.
The rise of sap is mainly caused by simple physical forces such as transpiration and root pressure, but commutation is done using energy.
