Question

The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.

A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2.

Based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water?
The contractions would increase.
The contractions would decrease.
The contractions would cease altogether.
The contractions would establish dynamic equilibrium.

Answer 1

The contraction will increase. The first option is the correct option.

What is the contractile vacuole?

It is an organ that helps to excrete excess water from the body of some protozoans such as paramecium.

The more excess water present in the organism, the more the contractile vacuole contracts to get rid of the water.

With distilled water, more water will enter the cell and this excess water will need to be gotten rid of. Thus, the contraction rate will increase.
