Unit 1: Photosynthesis and Plants

Front

What is chlorophyll and its role in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants. It absorbs sunlight and converts it into chemical energy during the process of photosynthesis.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce their own food, primarily in the form of glucose.

Front

What is a dependent variable in an experiment?

Back

A dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

Front

What is a controlled variable?

Back

A controlled variable is a factor in an experiment that is kept constant to ensure that the results are valid and reliable.

Front

What does the suffix '-synthesis' mean?

Back

The suffix '-synthesis' means 'putting together'.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a type of sugar) and oxygen.

Front

What is the significance of sunlight in photosynthesis?

Back

Sunlight provides the energy required for the photosynthesis process, allowing plants to convert carbon dioxide and water into glucose.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs, containing chlorophyll and other pigments that capture light energy.

Front

Explain the importance of water in photosynthesis.

Back

Water is essential for photosynthesis as it is one of the raw materials used in the process, and it also helps maintain plant structure and function.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
