Final answer:
Bulk transport is indeed necessary for transporting large polar molecules into or out of cells as these molecules cannot typically pass directly through the cell membrane due to size or polarity.
Step-by-step explanation:
The statement 'Bulk transport is required for the transport of large polar molecules into or out of the cells' is true. Bulk transport refers to the methods by which cells move substances that are too large or too polar to pass through the cell membrane, by processes that involve the formation of vesicles. Two main types of vesicle transport include endocytosis, where materials are brought into the cell, and exocytosis, where materials are expelled from the cell. Both of these processes require energy, making them forms of active transport. While some small and uncharged molecules can pass directly through the cell membrane, large or polar molecules such as proteins, glucose, and amino acids typically require assistance from transport proteins or vesicle transport to enter or exit a cell.
