Photosynthesis

Front

What is photosynthesis?

Back

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

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (C6H12O6), along with oxygen (O2) as a byproduct.

Front

In which organelle does photosynthesis occur?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the blue and red wavelengths, and reflects green light.

Front

What is the role of sunlight in photosynthesis?

Back

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

Front

What is an autotroph?

Back

An autotroph is an organism that produces its own food from inorganic substances, using light or chemical energy, such as plants.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and instead obtains nutrients by consuming other organisms.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

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 heterotrophs.
