Final answer:
The statement is true. Pinocytosis, often referred to as 'cell drinking', absorbs smaller molecules, as opposed to phagocytosis, which engulfs larger particles, including whole cells. Therefore, particles taken up during pinocytosis are indeed smaller than those involved in phagocytosis.
Step-by-step explanation:
The statement "The particles taken up during pinocytosis are smaller than those in phagocytosis" is true. Both phagocytosis and pinocytosis are methods of endocytosis where cells absorb particles from their surroundings. However, they operate on different scales. Phagocytosis is a process where the cell engulfs larger particles, such as whole cells.
On the other hand, pinocytosis often referred to as 'cell drinking', is a process that involves cells absorbing smaller molecules, including water, which they need from the extracellular fluid. As such, pinocytosis results in much smaller vesicle creation compared to phagocytosis, thus substantiating the assertion that the particles involved in pinocytosis are indeed smaller than those involved in phagocytosis.
