passive transport
Active trasnport
active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration-against the concentration gradient. Active transport requires cellular energy to achieve this movement.
passive transport is a type of cellular transport in which substance such as ions and molecules move down their concentration gradient and this proccess doesnt require energy

movement of water molecules through a semipermeable membrane. (from area of higher water concentration to an area of lower water concentration
it is a type of diffussion that doesnt require energy or transport proteins to transport molecules
doesnt require any energy
The sodium-potassium pump works by transporting sodium and potassium against their concentration gradients.
Exocytosis is the opposite of endocytosis which cells excrete waste and other large molecules from the cytoplasm to the cell exterior
transportation of molecules down conentration gradient using transport proteins
It is a type of active transport which cells take in substances from outside of the cell by engulfing them in a vesicle
It requires chemical energy (ATP)
it moves against concentration gradient (from low to high concentration)
it goes down concentration gradient(from high to low)
