What functions might the three types of diffusion serve in a multicellular organism?
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.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
What are the two types of possive transport?
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.
What is falicitated diffusion?
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.
What transport mechanism do one celled colonial and simple multicellular organisms rely on?
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.
The type of transport that requires no cellular energy?
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.
An example of passive transport process is?
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.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
How does diffusion take place in the body?
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy

What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
How does faciliated diffusion differ from simple diffusion?
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.
What are the two types of possive transport?
