Webbinside the phloem. This translocation occurs via the plasma membrane of the sieve tubes, which are composed of a series of connected sieve elements. The mechanism of the longitudinal assimilate movement in sieve tubes has been explained by two different models of phloem loading: 1. Symplastic loading, 2. Apoplastic loading.

Webb21 maj 2024 · Phloem translocation is the process of transportation of the produced food ( sucrose) in plants. Thus, sources in plants are the sites that are capable of producing sucrose; plant leaves are the main sources in plants. Whereas, the sites such as stems and roots which store the produced food are the sinks of the plant. CONTENTS 1. WebbFrom the late 1950s, Colin Pittendrigh, Professor at Princeton and Stanford, became a great advocate of Bünning’s work.
