What is a dependent variable in an experiment?

Back

The dependent variable is the variable that is measured or observed in an experiment, which is affected by changes in the independent variable.

What is an independent variable in an experiment?

Back

The independent variable is the variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

What is the significance of controlling variables in an experiment?

Back

Controlling variables ensures that the experiment tests only the effect of the independent variable on the dependent variable, leading to valid and reliable results.

What can you infer about the relationship between fungi and plants based on experimental data?

Back

Fungi and plants may have a symbiotic relationship, as they can both affect each other's growth and health.

How do you determine the independent variable from a graph?

Back

The independent variable is typically plotted on the x-axis of a graph, while the dependent variable is plotted on the y-axis.

Front

What does it mean for a plant to be vascular?

Back

A vascular plant has specialized tissues (xylem and phloem) for transporting water, nutrients, and food throughout the plant.

Front

What is the purpose of a control group in an experiment?

Back

A control group serves as a baseline to compare the effects of the independent variable, helping to isolate the variable being tested.

Front

How can you identify the dependent variable from a graph?

Back

The dependent variable is usually plotted on the y-axis and represents the outcome that is measured in response to changes in the independent variable.

Front

What is the importance of replication in scientific experiments?

Back

Replication increases the reliability of results by ensuring that findings are consistent and not due to random chance.
