In protists, the processes involved in the transport of materials include diffusion, active transport, phagocytosis, and pinocytosis. Diffusion allows small molecules to passively move across the cell membrane, while active transport uses energy to move materials against a concentration gradient. Phagocytosis involves the engulfment of solid particles by the cell, while pinocytosis facilitates the uptake of fluids and dissolved molecules.
Amoebas use phagocytosis to take in food and other materials. During phagocytosis, the amoeba extends its cell membrane around the particle and engulfs it, forming a food vacuole. The food is then digested inside the vacuole.
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins
The process by which materials are engulfed by the cell membrane and brought into the cell is called endocytosis. It involves the formation of vesicles that surround the material to be taken in and then fuse with the cell membrane to release the contents into the cell. There are two main types of endocytosis: phagocytosis, for larger solid particles, and pinocytosis, for smaller liquid particles.
The process where the plasma membrane forms a pocket to bring in solid materials is called endocytosis. This involves the engulfment of particles by the membrane to create a vesicle inside the cell for further processing.
These are all types of active transport involving the movement of materials across a cell membrane. Phagocytosis refers to the process of engulfing large particles, pinocytosis involves taking in fluids or solutes, and exocytosis is the release of materials from a cell.

Phagocytosis involves the engulfment of solid particles by the cell, while pinocytosis facilitates the uptake of fluids and dissolved molecules.
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.

Phagocytosis is the process by which cells engulf and digest large particles, such as bacteria or cellular debris, through the formation of vesicles called phagosomes. Exocytosis, on the other hand, is the process by which cells release substances stored in vesicles outside the cell by fusing the vesicle membrane with the cell membrane. In phagocytosis, material is ingested, while in exocytosis, material is released.

This process is called endocytosis, where the cell membrane invaginates to form vesicles that transport materials into the cell. These vesicles can then fuse with other organelles or transport materials to other parts of the cell.
Osmosis transports water molecules across a partially permeable membrane, such as a cell membrane. It does not transport other types of materials, like ions or larger molecules.
