Lesson 5: Matter & Growth

Matter is anything that has mass and takes up space.

True

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

We measured plant growth by observing the increase in the plant's weight.

True

If the factor is present and the plant grows, it indicates that the factor is necessary. If the factor is absent and the plant does not grow, it further supports this.

The main factors necessary for plant growth include light, air, water, and soil.

Light is essential for photosynthesis, the process by which plants convert light energy into chemical energy.

Water is crucial for transporting nutrients, maintaining cell structure, and facilitating photosynthesis.

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.
