Front

What is the dependent variable in an experiment?

Back

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

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process that removes carbon dioxide from the atmosphere and converts it into glucose using sunlight.

Front

What is the primary function of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell, providing protection and support.

Front

What structure protects plant cells and gives them their shape?

Back

The cell wall is the tough exterior that protects plant cells and maintains their shape.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs sunlight, which is essential for the process of photosynthesis.

Front

What is the process by which plants convert sunlight into energy?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy in the form of glucose.

Front

What is the function of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP (energy) through cellular respiration.

Front

What is the difference between a plant cell and an animal cell?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not have these structures.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
