Detailed explanation-1: -Three transport processes that do not require energy are; diffusion, osmosis and facilitated diffusion.

Detailed explanation-2: -Xylem tissues are water conducting vascular tissues which are made up of dead cells. These tissues do not require energy for transporting water and minerals from roots to the leaves. The transportaion of water and minerals takes place through the transpirational pull.

Detailed explanation-3: -Complete answer: The storage of metabolic products is not a function of xylem.

Detailed explanation-4: -Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.

Detailed explanation-5: -Xylem cells form long tubes that transport materials, and the mixture of water and nutrients that flows through the xylem cells is called xylem sap. These substances are transported through passive transport, so the process doesn’t require energy.
