Sucrose Symplast Route Phloem Moves Sieve Describe Loading

The symplast route for phloem loading involves sucrose moving through the cytoplasm of mesophyll cells into sieve tubes by diffusion, with water following by osmosis, creating hydrostatic pressure for mass flow.

La ruta simplástica para la carga del floema implica que la sacarosa se mueva a través del citoplasma de las células mesófilas a los elementos del tubo criboso por difusión, y el agua la siga por ósmosis, creando presión hidrostática para el flujo masivo.

Front Describe the symplast route for phloem loading and explain how it occurs
Back Symplast route for loading:
  • Sucrose moves thru cytoplasm of mesophyll cells into sieve tubes by diffusion thru plasmodesmata
  • Sucrose ends up in sieve elements and water follows by osmosis
  • Hydrostatic created that moves sucrose thru phloem by mass flow
