Diffusion. With the need of energy, it would be called active transport.
Passive transport, such as diffusion or osmosis.
Passive transport.
1. Passive transport processes describe substances moving from regions of higher to lower concentrations without the use of energy. This includes diffusion, which is the basic movement of substances from an area of higher to lower concentration, as well as osmosis, which is the movement of water from an area of higher to lower concentration. Facilitated diffusioninvolves the diffusion of solutes or water through channel proteins in the plasma membrane.2. Active transport processes involve the movement of solute against a gradient, meaning it moves from areas of lower to higher concentration, and requires energy in the form of ATP. Transport proteins assist in moving these substances in and out of the membrane.3. Vesicular transport involves processes that use vesicles or other bodies in the cytoplasm to move large molecules or particles across the membrane. Endocytosis involves the capture of a substance outside of the cell when the membrane engulfs it. Two of these processes are called phagocytosis, in which the membrane engulfs solid material, and pinocytosis, which involves the membrane folding inward to form a channel for liquids to enter.
I've transport.
Beacuse without it life would not be worth living!
simple diffusion, facilitated diffusion, and osmosis (water)
passive transport
Passive transport is when substances move past the membrane without using any energy.
Passive transport is when substances move past the membrane without using any energy.
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
Osmosis across a selectively permeable membrane allows water across but disallows other particles across the membrane.

Passive transport.
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
This type of movement is called simple diffusion.
