The process of cellular input .. The process of transferring materials with relatively large molecules from outside the cell into the inside of the cell membrane

The process of cellular input
the definition:
The process of transferring substances with relatively large molecules from outside the cell into their cells across the cell membrane.
Steps to occur:
A part of the cell membrane is folded to surround the material, forming a cyst or a gap around it. This bag then moves into the cytoplasm. If the input material is solid, the transfer is called bile.
