What is the primary driving force for the movement of nutrients in phloem?

Step 1: Understand that phloem is a part of a plant that transports nutrients, especially sugars.
Step 2: Learn that sugars are made in the leaves of the plant through photosynthesis.
Step 3: Know that sugars are actively transported into the phloem, which means energy is used to move them in.
Step 4: Realize that when sugars enter the phloem, they create a higher concentration of sugar in that area.
Step 5: Understand that this higher concentration creates pressure in the phloem.
Step 6: Learn that the pressure pushes the sugary solution through the phloem to other parts of the plant.
Step 7: Conclude that the movement of nutrients in phloem is driven by this pressure flow mechanism.
