What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Why is photosynthesis important for life on Earth?

Back

Photosynthesis is important because it produces oxygen, which is essential for most living organisms, and it forms the base of the food chain by providing energy for plants and, subsequently, for herbivores and carnivores.

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is necessary for photosynthesis.

What is a dependent variable in an experiment?

Back

The dependent variable is what you measure or record in an experiment; it changes in response to the independent variable.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that you change or manipulate in an experiment to observe its effect on the dependent variable.

What does it mean when we say a plant's leaves are green?

Back

A plant's leaves appear green because the green light is reflected back to our eyes, while other colors of light are absorbed.

Front

What is a controlled experiment?

Back

A controlled experiment is one in which all variables are kept constant except for one independent variable, allowing for a clear observation of its effects.

Front

How many variables should be tested at a time in a controlled experiment?

Back

In a controlled experiment, only one variable should be tested at a time to ensure that the results are due to that variable alone.

Front

What is the significance of water for plant growth?

Back

Water is essential for plant growth as it is a key component of photosynthesis, helps transport nutrients, and maintains cell structure.

What is the effect of sunlight on plant growth?

Back

Sunlight provides the energy needed for photosynthesis, which is crucial for plant growth and development.
