Cell Transport Mechanisms

This video from Moomoomath and Science covers essential life science vocabulary, including active transport, passive transport, osmosis, diffusion, and endocytosis. Active transport requires energy to move substances across a cell membrane, while passive transport does not. Osmosis is the diffusion of water across a membrane, and diffusion involves particles moving from high to low concentration. Endocytosis is a type of active transport where large objects move into a cell. The video concludes with a reminder to subscribe for daily math and science content.
