WebbPhloem transport is known as translocation, and it provides all the parts of the plant with the sugars they need for cellular respiration. When we describe translocation, we often talk about the movement of sucrose from a source to a sink. But what does this actually mean? WebbThe phloem transports amino acids and sucrose throughout the plant. This process occurs between the sources and sinks. It is similar to where substances are created and where they are used or deposited. This entire process is known as translocation. This entire process is known as translocation.
