Prokaryotes (like bacteria) tend to rely on simple diffusion for the most part. Simple diffusion is the movement of nutrients from an area of higher concentration to an area of lower concentration in order to reach equilibrium.
Eukaryotes (our cells are eukaryotes) can and do rely on simple diffusion, but are capable of performing active transport, in which specific membrane proteins essentially "pump" nutrients into or out of the cell as needed.
Simple diffusion usually takes a long time. If your body relied on simple diffusion, it would take years for an oxygen molecule in your lungs to get to your fingertips! We have cells that can take up, and distribute nutrients where they are needed, and when they are needed, in a reasonable amount of time.
Bacteria and other small prokaryotes can rely on simple diffusion, because they have very small volumes, so molecules will diffuse slowly across their membranes, but the molecules do not have to go very far because of how small the bacteria are.

What is responsible for recycling dead cells?
The process of recycling dead cells is carried out by specialized cells called phagocytes. These cells engulf and break down the dead cells, recycling their components into new molecules that can be used by the body for energy or building new cells.
What is made up of primarily dead cells?
Dust is primarily made up of dead cells.
What does white blood cells do to dead cells?
White blood cells help to clear away dead cells by engulfing and breaking them down through a process called phagocytosis. This helps to remove dead cells and prevent the buildup of cellular debris, which can be harmful if left unchecked.
Do things that are dead still have cells?
Yes, things that are dead still have cells. These cells begin to die after somatic death (whole body death).
Are human cheek cells are animal cells?
Generally Human Cheek cells (as with skin cells) are dead on the outermost layers, and still alive on the deeper layers. So the cheek cells are dead even before you take them out of your mouth.
Does osmosis occur in dead cells?
if the membrane is intact and there is a change of concentration of solut or solvent, osmosis should happen.
What cellular function is missing in dead cells Osmosis Diffusion Active transport (solute pumping) or dialysis?
The cellular function that is missing in dead cells is active transport (solute pumping). Active transport requires energy to move molecules against their concentration gradient, a process that cannot occur if the cell is no longer metabolically active. Osmosis, diffusion, and dialysis can still occur in dead cells as they do not require energy expenditure by the cell.
Have dead cells why is it an advantage to on the surface of the body?
Why is it an advantage to have dead cells on the surface of the body? Why is it an advantage to have dead cells on the surface of the body?
What are the peoples nails made of?
dead skin cells

Which two examples of dead cells?
Fibres(substances used to digest food) and cells of dead organisms are examples.
Can dead brain cells multiply?
Dead brain cells can't multiply.
When was Dead Brain Cells created?
Dead Brain Cells was created in 1986.
When was Dead Embryonic Cells created?
Dead Embryonic Cells was created in 1991.
What is the name for removing dead cells?
Macrophages remove dead cells by phagocytosis.
Do pieces of hair have cells?
Yes, but they are actually dead cells. Your hair and nails are basically a secretion of dead cells.
When cells in food die does the good get rotten?
This isn't always true for rotten food. There may be dead cells in foods, however they may be well preserved. This prevents any bacterial or fungal growth to occur.
