Question

What are the steps of endocytosis?

Answer 1

The cell recognizes the presence of a material to be engulfed,
The cell membrane curves to the inside of the cell as the cytoplasm underneath becomes more soluble.
This cell membrane surrounds the particle to be engulfed.
A vesicle is formed by the en around this particle.
This vesicle pinches off to the cytoplasm inside the cell.
