Simple diffusion: Allows for the exchange of small, non-polar molecules across cellular membranes, important for nutrient uptake and waste removal. Facilitated diffusion: Facilitates the transport of specific large or charged molecules by utilizing carrier proteins embedded in cellular membranes, crucial for maintaining cellular homeostasis and signaling. Active transport: Uses cellular energy to move molecules against their concentration gradients, enabling the absorption of essential nutrients and the removal of waste products from cells.
Simple diffusion
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
These organisms use simple diffusion as a transport mechanism.This is possible because of the small size of the organisms. Diffusion is effective over small distances but as size increases it becomes less and less efficient.
Passive transport requires no cellular energy as it relies on the movement of molecules down their concentration gradient, such as diffusion and osmosis. These processes occur spontaneously to maintain equilibrium within the cell.
One example of a passive transport process is simple diffusion, where molecules move across a membrane from an area of higher concentration to an area of lower concentration without the need for energy input.

both need transport protein
Simple diffusion
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
