Question

what is plant growth in the experiment exploring the effect of water on plant growth?control groupconstantindependent variabledependent variable

Explanation:

In an experiment testing how water affects plant growth, the independent variable is the factor being manipulated (water amount/availability). The dependent variable is the outcome being measured, which changes in response to the independent variable. Plant growth is the measured result that depends on the water provided, so it is the dependent variable. A control group is a set of subjects not exposed to the test variable, and a constant is a factor kept unchanged throughout the experiment, neither of which describes plant growth here.

Answer:

Dependent variable
