Model Cell Experiment

Front

A laboratory setup of a model cell with beaker, distilled water, dialysis tubing, and starch solution.

Back

If starch (solute) cannot move through a membrane, the mass of the model cell will most likely increase after 24 hours.

What organelle do Prokaryotes lack that houses and protects DNA?

Back

Prokaryotes lack a nucleus.

Front

Cells often need to take in materials from their environment, many of which are found in lower concentrations outside the cell compared to inside the cell. In order to do this, cells must use the energy from ATP to move these materials...

Back

Against the concentration gradient (L to H) through active transport.

Controlling passage of materials

Front

Dialysis tubing was filled with an unknown solution to represent a "cell" and submerged in distilled water and increasingly saline solutions.

Back

The dialysis tubing is impermeable to Na+ and Cl- ions.

Front

In an isotonic environment, the cell would not change its mass.

Back

This occurs in a solution at approximately 0.65M.

The movement of solutes from area A to area B through a selectively permeable membrane is an example of:

Modifies, sorts, and packages proteins and other materials for storage or release from the cell.
