Cell Transport Notes1. Fill in the chart you see on the board:
CELL TRANSPORT RECAP:
2. A cell must be able to transport materials in order to be able to get what they need.
3. Recall that the cell membrane is the specific cell organelle that materials pass through. It is considered to be ____Selectively permeable________.
4. Molecules are selected based on the size of the ___Pores_______, size of the ___Molecules___, and the Chemical Composition of the molecule.
5. Cell transport can either be __Passive______ or ______Active_______ based on whether or not energy is required.
PASSIVE TRANSPORT:6. __Passive Transport ____ is the movement of a
substance across the cell membrane without the cell having to use any energy.
7. This is because the particles move from an area of ____High________ concentration to an area of ___Low Concentration_.
8. Diffusion is a type of passive transport and involves small particles moving from an area of _High________ concentration to an area of ____Low_____ ___Concentration______.
9. Osmosis is the diffusion of _WATER______ through a cell membrane. Water molecules move from an area of __High________ concentration to an area of ___Low_______ concentration.

1.ACTIVE TRANSPORT OF SMALL PARTICLES10.Active transport requires __ENERGY_______ 11.Sometimes the cell must use __energy_____ to move
molecules against the normal direction of diffusion. This means the particles move from an area of ___Low___ concentration to a __High________ concentration. The energy used in the cell comes from _ATP______.
ACTIVE TRANSPORT OF LARGE PARTICLES:
12.In order to move large particles, the cell uses two different processes to move particles _Into___ the cell and ____Out of_____ the cell.
13.Endocytosis involves bringing particles _Into___ the cell.(The prefix “endo” means __Into_)
14.Exocytosis involves Moving ___ particles out of the cell. (The prefix “exo” means _Exit__)
