what is meant by translocation?

Translocation generally means the movement of something from one place to another in a cell or organism.

Basic meaning

• In biology, “translocation” is the process or event in which a substance or a piece of genetic material changes its location inside a living system.

• The exact meaning depends on context, especially whether the topic is plants or chromosomes.

In plants (transport of food)

• In plant physiology, translocation is the movement of nutrients (mainly sugars made in leaves) through the phloem from one part of the plant to another.

• These nutrients move as phloem sap and can travel upward or downward to growing regions, roots, fruits, and storage organs.

In genetics (chromosome change)

• In genetics, translocation is a chromosome change where a segment of one chromosome breaks off and attaches to a different chromosome or a new position on the same chromosome.

• Such chromosomal translocations can be balanced (no net gain or loss of genetic material) or unbalanced and may be linked to disorders, including certain leukemias.

TL;DR:
“Translocation” means a change of location. In plants it refers to the movement of food through the phloem, and in genetics it refers to pieces of chromosomes breaking and reattaching elsewhere.
