Photosynthesis Review

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 are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O), along with sunlight.

Front

What is the main product of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen (O2).

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: CO2 + H2O + light energy → O2 + C6H12O6 (glucose).

Front

What role does sunlight play in photosynthesis?

Back

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

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, typically through photosynthesis.

Front

What gas is released during photosynthesis?

Back

Oxygen (O2) is the gas released during 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 heterotrophs, forming the base of the food chain.

Front

What is chlorophyll?

Back

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