Solidifying Activities

What will we discuss today...

• Effects of Hypotonic, Hypertonic and Isotonic solutions on animal cells

• Effects of Hypotonic, Hypertonic and Isotonic solutions on plant cells

Let's answer a few questions to check your memory

Multiple Choice

When an animal cell is immersed in a hypertonic solution, the water from the surrounding will move into the cell.

• True

• False

Multiple Choice

When a plant cell is immersed in a hypotonic solution, the plant cell will be turgid.

• True

• False

Multiple Choice

What is the effect when putting animal cells in the hypotonic solution?

• cell will be lysed

• cell will be shrivelled

• cell will be turgid

• cell will be flaccid

Multiple Select

In your opinion, why we should not drink seawater?

• our cell body will be shrivelled

• our cell body will be lysed

• our cell body will be shrinking

• our cell body will be burst

Multiple Choice

How do water molecules move?

• diffuse from low water potential to high water potential

• diffuse from low water potential to low water potential

• diffuse from high water potential to low water potential

Multiple Choice

When an animal cell is immersed in a hypertonic solution, the cell will be shriveled and shrinked.

• True

• False

Multiple Choice

What happen to a plant cell if it immersed in the hypotonic solution?

• plasmolysed

• flaccid

• turgid

• lysed

Multiple Choice

A plant cell will be flaccid if it is immersed in hypertonic solution.

• True

• False

What we have discuss today...

• Hypertonic solution : Plant cell = plasmolysed, Animal cell = Shrink, Shrivelled

• Hypotonic solution : Plant cell = Turgid, Animal cell = Lysed (burst)
