A biology student wanted to study the effect of fertilizer on the growth of tomato plants. He placed four of
the same type of tomato plants into separate containers, each containing the same amount of soil. Each
pot received a different watering solution containing varying amounts of fertilizer.
The table below shows the average height of the plants by the end of one week.

Which of the plant groups is the control group?

Any substance of earthy or man-made origin applied to soil or plant tissues to provide plant nutrients is referred to as fertilizers. It's possible to distinguish fertilizers from spreading agents.

The biology student is studying the effect of fertilizers on plants. Fertilizers increase the growth of the plant, and they also affect the soil of the plant in which they grow.

There are three groups of plants that are used. The growth of the first plant is O and 3.0. The growth of the second plant is 5, 3.2, 3, and 10 and the growth of the third plant is 10, 4.4, 20, and 5.0.

By seeing the Table, we can assume that the growth of plant group 1 is most affected and all other plants have similar.

Thus, the plant group is 1.
