💡 Key Idea

The Core Reaction

Plants cook their own food.

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. The overall equation is:

↳ Photosynthesis turns light, water, and CO₂ into food and oxygen.

📖 Definition

What Exactly Is Photosynthesis?

A precise definition.

Photosynthesis is the biochemical process in which autotrophs use sunlight to synthesise glucose from carbon dioxide and water, releasing oxygen as a by-product. It is the primary source of all organic matter on Earth.

↳ It is the foundation of almost every food chain.

⭐ Important Fact

Where It Happens: The Chloroplast

Inside the green factory.

Photosynthesis occurs in chloroplasts, organelles found in plant cells. Chloroplasts contain chlorophyll, the green pigment that absorbs light energy, mainly in the blue and red parts of the spectrum.

↳ Chloroplasts are the site; chlorophyll is the light catcher.

Photosynthesis: How Plants Make Food

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. It occurs in chloroplasts and involves two stages: light-dependent reactions and...

  • Photosynthesis is the process by which plants convert light energy into chemical energy (glucose).
  • The overall equation is 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.
  • It occurs in chloroplasts, which contain the green pigment chlorophyll.

What is the primary purpose of photosynthesis in plants?

Beginner
A To release energy from food B To transport nutrients throughout the plant C To absorb water from the soil D To produce food (glucose) using sunlight
Show answer & explanation

To produce food (glucose) using sunlight

Photosynthesis is the process by which plants make their own food (glucose) using sunlight, carbon dioxide, and water.

Which gas do plants take in from the air during photosynthesis?

Beginner
A Carbon dioxide B Hydrogen C Oxygen D Nitrogen
Show answer & explanation

Carbon dioxide

Plants absorb carbon dioxide from the air through small openings called stomata.

What is the main source of energy for photosynthesis?

Beginner
A Oxygen B Soil nutrients C Water D Sunlight
Show answer & explanation

Sunlight

Sunlight provides the energy needed to drive the chemical reactions of photosynthesis.

Which pigment in plants captures light energy for photosynthesis?

Intermediate
A Melanin B Hemoglobin C Carotene D Chlorophyll
Show answer & explanation

Chlorophyll

Chlorophyll is the green pigment that absorbs light energy, primarily in the chloroplasts of plant cells.
