GENERAL HISTOLOGY

Detailed explanation-1: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.

Detailed explanation-2: -Transportation through plasma membrane occurs by simple diffusion, osmosis and facilitated diffusion. These are passive transport mechanisms.

Detailed explanation-3: -There are three passive transportation methods-diffusion, facilitated diffusion and osmosis.

Detailed explanation-4: -Active transport is the process in which ions or other molecules move across a semipermeable membrane into an area of higher concentration. This process requires energy and enzymes to work, which indicated by the name “active” transport.

Detailed explanation-5: -Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space.
