Passive transport
Understand the processes of osmosis and diffusion; Define tonicity and describe its relevance to passive transport Plasma membranes must allow
Other than simple and facilitated diffusion, osmosis and filtration are two other techniques that work on the principle of passive transport They are also Transport Without Energy Expenditure By The Cell Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell
น้ำตกคอหมูย่าง Passive transport does not require energy down concentration gradients Often, substances have to be moved from a low to a high concentration Passive transport is the movement of ions and molecules along the concentration gradient without the application of any external energy
