1. Define phototrophy and explain its significance in

biological systems.

Answer: Phototrophy is the process by which organisms

harness energy from light to drive metabolic reactions. This

is significant as it enables the synthesis of organic

compounds necessary for growth and survival.

Rationale: This question tests the students' understanding

of the basic concept of phototrophy and its role in

biological systems.

2. Discuss the difference between phototrophs and

chemotrophs in terms of energy acquisition and metabolic

processes.

Answer: Phototrophs obtain energy from light, whereas

chemotrophs obtain energy from the oxidation of organic

or inorganic compounds. Metabolic processes in

phototrophs involve photosynthesis, while chemotrophs

employ various enzymatic reactions for energy acquisition.

Rationale: This question aims to assess students' ability to

differentiate between phototrophs and chemotrophs based

on energy acquisition and metabolic processes.
