EOU Exam on Thursday, May 1st

Lesson 2

Diffusion & Concentration

Learning Intention

Students will be able to discover key concepts of diffusion through experiments and apply their discoveries to the function of the cell membrane.

Success Criteria

Review diffusion key concept and vocabulary through regents questions.
Determine the direction of diffusion based on the concentration.
Apply my knowledge to a cell structure.
Demonstrate my knowledge of concentration gradient by answering regent questions.

Reminders:

Tutoring 9th period with Ms. Angarola
Tutoring after-school Thursdays with Mr. Pinho in A-301

NGSS Standard

Each cell is covered by a membrane that performs a number of important functions for the cell. These include: separation from its outside environment, controlling which molecules enter and leave the cell, and recognition of chemical signals. The processes of diffusion and active transport are important in the movement of materials in and out of cells. (1.2g)

🔑Key Concept:

1) Diffusion Concentration Gradient: Molecules naturally move from a high concentration to a low concentration of molecules. This does not require energy. This is called passive transport.

2) Equilibrium:

Equal number of molecules on both sides of the semi-permeable membrane.
