Question

Assertion (A): Photosynthesis is an anabolic process.

Reason (R): It involves the synthesis of complex organic molecules from simpler substances.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation:

The assertion is true because photosynthesis is an anabolic process, meaning it is a constructive metabolic pathway that builds larger molecules. The reason is also true and provides the correct explanation because it defines what makes a process anabolic: it uses energy to synthesise complex organic compounds (like glucose) from simpler inorganic substances (like carbon dioxide and water).
