Unicellular organisms eliminate wastes by simple diffusion from the body surface into surrounding water. Complex multicellular organisms use specialized organs for excretion.

The biological process involved in removing harmful metabolic wastes is called excretion.

Translocation in phloem is achieved by utilizing energy, with substances like sucrose transferred using energy from ATP. This increases osmotic pressure, causing directional movement of materials in the phloem to tissues with lower pressure, allowing for material transport as per ...

The phloem transports amino acids and other substances, especially delivering them to storage organs of roots, fruits, seeds, and growing organs.

The movement of products of photosynthesis is called translocation, and it occurs in the phloem, a part of the vascular tissue.

Root pressure is more important at night, while during the day, when stomata are open, transpiration pull becomes the major driving force for the movement of water in the xylem.

Transpiration aids in the absorption and upward movement of water and dissolved minerals from roots to leaves, facilitated by the suction effect created during leaf cell evaporation.

Water lost through stomatal transpiration is replaced by water from xylem vessels in the leaf, driven by the suction created through evaporation from leaf cells.
