Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment found in plants that absorbs light energy for photosynthesis.

Front

What is the general equation for photosynthesis?

Back

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

Front

Why do leaves appear green?

Back

Leaves appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

Front

Do animal cells have chloroplasts?

Back

No, animal cells do not have chloroplasts; they are found in plant cells.

Front

What is the role of sunlight in photosynthesis?

Back

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

Front

What is the difference between photosynthesis and chemosynthesis?

Back

Photosynthesis uses sunlight to produce glucose, while chemosynthesis is a process used by some bacteria to produce glucose without sunlight, using chemical reactions.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is produced as a byproduct of photosynthesis?

Back

Oxygen (O₂) is produced as a byproduct of photosynthesis.

Front

What is the significance of photosynthesis in the ecosystem?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for plants and, indirectly, for animals.
