Goal 2

The learner will develop an understanding of the physical, chemical and cellular basis of life.

Objective 2.03

Investigate and analyze the cell as a living system including:

  • Maintenance of homeostasis.
  • Movement of materials into and out of cells.
  • Energy use and release in biochemical reactions.

Resources aligned to this objective

What happens to plant cells in hypertonic and hypotonic solutions?
Students will be using actual laboratory examples and classroom examples to understand the movement of molecules across the cell membrane. Looking at weight change in potato cells, color change in diffusion, and the shrinking of living tissue will allow the student to experience diffusion and osmosis.
