Bulk transport mechanisms are important for plant and animal cells since every cell requires a constant supply of nutrients and oxygen to produce energy through respiration. Bulk transport allows for the cell to transport large amounts of materials. These methods specifically help cells take in nutrients from their surroundings, release signaling molecules to interact with nearby cells, or uptake specific particles from the fluid outside the cell. Additionally, bulk transport is crucial for balancing ions and molecules inside and outside the cell. This helps eliminate waste and toxins, ensuring the proper functioning of multicellular organisms.
