passive (1/2)
active (2/2)

Explanation:

• Osmosis: It is the movement of water molecules from an area of high water concentration to an area of low water concentration across a semi - permeable membrane. It does not require energy (ATP), so it is a passive process.
• Filtration: It is the movement of substances (usually small molecules) through a membrane due to a pressure gradient. It does not use ATP, so it is passive.
• Diffusion: It is the movement of molecules from an area of high concentration to an area of low concentration. It is a passive process as it does not require energy input.
• Endocytosis: It is the process by which cells engulf substances (either large molecules, particles or other cells). It requires energy (in the form of ATP) to form vesicles, so it is active.
• Phagocytosis: A type of endocytosis where cells engulf large particles (like bacteria). It is an active process as it needs energy for vesicle formation and movement.
• Pinocytosis: A form of endocytosis where cells take in liquid and dissolved substances. It is active as it requires energy.
• ATP consumption: Since ATP is the energy currency of the cell, any process that consumes ATP is an active process.
• Exocytosis: It is the process by which cells release substances (like proteins, waste products) by fusing vesicles with the plasma membrane. It requires energy (ATP), so it is active.

Answer:

• Passive: Osmosis, Filtration, Diffusion
• Active: Endocytosis, Phagocytosis, Pinocytosis, ATP consumption, Exocytosis
