Photosynthesis is the process utilized by plants, algae, and certain bacteria to harness energy from sunlight and convert it into chemical energy stored in glucose, a type of sugar.
MCQs
1. Which organisms primarily perform photosynthesis?
A) Animals
B) Plants
C) Fungi
D) Bacteria
Answer: B) Plants
Explanation: While certain bacteria and algae also perform photosynthesis, plants are the primary organisms known for converting light energy into chemical energy through this process.
2. What is the main purpose of photosynthesis?
A) To produce oxygen for the planet
B) To break down organic waste
C) To convert light energy into chemical energy
D) To synthesize proteins from amino acids
Answer: C) To convert light energy into chemical energy
Explanation: The main purpose of photosynthesis is to convert solar energy into chemical energy (in the form of glucose) that plants can use to grow, develop, and reproduce.
3. What type of energy do plants use to perform photosynthesis?
A) Thermal energy
B) Mechanical energy
C) Light energy
D) Electrical energy
Answer: C) Light energy
Explanation: Plants use light energy, primarily from the sun, as the energy source to drive the photosynthesis process.
4. What is the primary chemical product of photosynthesis?
A) Oxygen
B) Carbon dioxide
C) Glucose
D) Water
Answer: C) Glucose
Explanation: The primary chemical product of photosynthesis is glucose, a simple sugar that serves as an essential energy source for plants and other organisms that consume plants.

Hydropower is a clean, renewable energy source that uses flowing water to generate electricity. It reduces pollution, conserves resources, and provides sustainable energy for homes and industries worldwide.
The Impossibility of Perpetual Motion Machines
Perpetual motion machines cannot work because they violate the laws of thermodynamics. Energy losses due to friction and other factors make it impossible to create a machine that runs forever without input.
Principles of the Law of Conservation of Mass
The law states that matter cannot be created or destroyed in a closed system. It can only change forms, ensuring mass remains constant during chemical reactions or physical transformations.
