This is called endocytosis.

Plants, fungi, and most bacterias.
Cell wall is present in plant cells, fungi, algae, and some bacteria. It provides structural support and protection to the cell, helping to maintain its shape and resist osmotic pressure.
The cell membrane contains phospholipids.
Cells may use mechanisms such as endocytosis to engulf and transport large molecules with the help of specialized transport proteins. These transport proteins facilitate the movement of large molecules across the cell membrane by forming vesicles that enclose the molecules and transport them to their destination within the cell. Once inside the cell, the vesicle can fuse with other cellular compartments to release the molecule for further processing or use.
sometimes bacterias.. Even if they're supposed to be stopped
The size, charge, and hydrophobicity of a molecule determine its ability to cross the plasma membrane. Small, nonpolar, and uncharged molecules can typically pass through the membrane via simple diffusion, while larger, charged, or hydrophilic molecules may require transport proteins or channels to facilitate their movement.
Exocytosis is the process by which large substances are moved out of the cell. This involves the fusion of vesicles containing the substances with the cell membrane, releasing the substances outside the cell.
This is called endocytosis.
The cell membrane folds around the molecule.
This process is called endocytosis. It involves the cell membrane engulfing and enclosing the molecule or particle in a vesicle to transport it into the cell.
The cell membrane
Every cells have a cell membrane. Sometimes, the cell membrane itself is also covered by a cell wall, but The cell membrane is still present in all cells.
