osmosis
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
This is called endocytosis.
permeation through the plasma membrane perhaps?
It is called passive diffusion.
Roads lol?

Cell membrane
can you control who is allowed to call you on skype?
The cell membrane regulates the passage of molecules in and out of the cell, allowing for selective permeability. It also maintains an internal environment distinct from the external environment. The cell wall provides structural support and protection, but it is porous and does not control the movement of substances in the same way as the cell membrane.
The process that allows movement of large molecules across a cell membrane is called endocytosis. In this process, the cell membrane engulfs the large molecules, forming a vesicle that brings them into the cell. There are different types of endocytosis, including phagocytosis for solid particles and pinocytosis for liquids. This mechanism enables cells to intake substances that cannot directly pass through the lipid bilayer of the membrane.
The cell membrane or plasma membrane in animals. The cell wall in plants.
