Endocytosis and Cellular Transport Concepts

The video tutorial explores how cells transport larger particles through processes like phagocytosis and pinocytosis, both forms of endocytosis. Phagocytosis involves engulfing large particles like bacteria, while pinocytosis involves engulfing fluids. The video also touches on the role of the cytoskeleton in these processes and highlights ongoing research in understanding the mechanisms of endocytosis.

What is the primary focus of the video regarding cellular transport?

• Facilitated diffusion

• Transport of ions

• Bulk transport of larger particles
