  1. 3 Moving Cellular Material • What do you think?

  2. Diffusion and osmosis are the same process. Cells with large surface areas can transport more than cells with smaller surface areas. 3 Moving Cellular Material • Do you agree or disagree?

  3. 3 Moving Cellular Material How do materials enter and leave cells? How does cell size affect the transport of materials?

  4. passive transport • diffusion • osmosis • facilitated diffusion • active transport • endocytosis • exocytosis • 3 • Moving Cellular Material

  5. 3 Moving Cellular Material Why the Veil? Look at the photo at the beginning of the lesson. A beekeeper often wears a helmet with a face-covering veil made of mesh. The openings in the mesh are large enough to let air through, yet small enough to keep bees out. In a similar way, some things must be allowed in or out of a cell, while other things must be kept in or out. How do the right things enter or leave a cell?

  7. Do you agree or disagree? Diffusion and osmosis are the same process. 3 Moving Cellular Material Disagree. Osmosis is the transport of water, and diffusion is the movement of other substances.

  8. Do you agree or disagree? Cells with large surface areas can transport more than cells with smaller surface areas. 3 Moving Cellular Material Agree. To move substances into and out of a cell efficiently, the surface area of a cell must be large compared to its volume.

  9. How do materials enter and leave cells? 3 Moving Cellular Material Materials enter and leave a cell through the cell membrane using passive transport or active transport.

  10. How does cell size affect the transport of materials? 3 Moving Cellular Material The ratio of surface area to volume limits the size of a cell. In a smaller cell, the high surface-area-to-volume ratio allows materials to move easily to all parts of a cell.
