Question

Quizplus · Accepted Answer

Mass flow is the movement of materials, such as nutrients and organic compounds, through the phloem due to the pressure created by the movement of water. This occurs as a result of active transport and diffusion processes within the phloem tissue, which transport materials from source regions (areas with high nutrient and organic compound production) to sink regions (areas where these materials are utilized for growth and energy). Factors such as temperature, light, and carbon dioxide levels can also influence the rate of mass flow in the phloem.
