Verified step by step guidance

Observe the sequence of images: The first image shows a particle outside the cell, the second image shows the cell membrane forming a pocket around the particle, and the third image shows the particle inside the cell.

Identify the process: The sequence of images depicts a process where the cell membrane engulfs a particle from the outside environment and brings it into the cell.

Understand the concept: This process is known as endocytosis, where the cell membrane wraps around the particle, forming a vesicle that transports the particle into the cell.

Differentiate from other processes: Exocytosis involves expelling materials from the cell, facilitated diffusion involves transport proteins helping move substances across the membrane without energy, and simple diffusion is the passive movement of particles from high to low concentration.

Conclude the identification: Based on the observation and understanding, the process shown in the images is endocytosis, as it involves the engulfing and internalization of a particle by the cell membrane.
