Diffusion is the general term.
Active Diffusion
cross our cell membranes
Particles move through cell membranes w/out the use of energy by cells.
The compound that allows materials to move through cell membranes by osmosis is water. Water moves freely through cell membranes to maintain osmotic balance within the cell.
Cell membranes do not make nutrients for cells. They are primarily responsible for controlling the entry and exit of substances into and out of the cell, as well as maintaining the cell's internal environment. Nutrients are typically obtained from the external environment through processes such as diffusion or active transport.
Osmosis
Not everything, no. It depends on the cell, some cell membranes are permeable to water (called osmosis) but not smaller particles like proteins. Whereas, some are permeable to proteins and other small particles but not to larger particles.
Yes, large hydrophobic molecules can cross cell membranes through passive diffusion.
Through facilitated diffusion
Hydrophilic proteins.
no, membranes are selectively permeable, letting somethings in and not others
Large particles that require energy to pass through cell membranes are called active transport. This process involves the movement of molecules or ions against their concentration gradient with the help of specialized proteins called pumps. Examples include the sodium-potassium pump and endocytosis.
