Facilitated diffusion
D
Simple diffusion
Verified step by step guidance1
Step 1: Observe the image carefully. It shows a cell membrane surrounding a particle outside the cell, then the membrane folding inward to engulf the particle, and finally the particle enclosed inside a vesicle within the cell.
Step 2: Understand the process depicted. The cell is taking in a particle by wrapping its membrane around it, forming a vesicle inside the cell. This is a form of active transport where the cell membrane engulfs external substances.
Step 3: Recall the definitions of the options: Exocytosis is the process of vesicles fusing with the membrane to release contents outside the cell; Endocytosis is the process of engulfing substances into the cell by vesicle formation; Facilitated diffusion and simple diffusion involve movement of molecules across membranes without vesicle formation.
Step 4: Match the observed process with the definitions. Since the cell is taking in a particle by forming a vesicle, this matches the definition of endocytosis.
Step 5: Conclude that the means of particle transport shown in the figure is endocytosis.
